I'm trying to display some data in my combobox, the strange thing is that the combobox displays all data that has 4 four columns (I only want to display 3 columns out the four) but its not displaying rows that only have three columns?
For example
Text File
Column1, Column2, Column3, Column4
I only want to display columns 1, 3 and 4 so I use the following coding
For Each Line As String In System.IO.File.ReadAllLines(Path)
If String.IsNullOrEmpty(Line) Then Continue For
Dim Columns() As String = Line.Split(New Char() {" "c}, StringSplitOptions.RemoveEmptyEntries)
If Columns.Count < 4 Then Continue For
Combobox1.Items.Add(Columns(0) & " " & Columns(2) & " " & Columns(3))
Next Line
But some of the rows only have
Column1, Column2 and Column3
Again I only want to display column1 and column3.
i have a table in sqlserver2005 which has currently following data...CUST_ID
[Code]...
Now i want to show highligted rows in a DGV according to there status, i mean show only rows of each cust_id "notpaid" status...the 1st "notpaid" status. like in cust_id 1, first "notpaid" row. I think now u got the idea wht exactly i m trying...please guide me step by step with proper code...actually i m new and i think myself as copy-paste king.
I have database like this [URL]but I will need to display only certain columns, which will depend on which user has logged in. Each user will have a unique ID, and so I want that that datagridview would only display the rows, which are for him, well have his ID, so that he couldn't see other users information, but only the one associated with him.I also need to output that user's forename and surename into label, it is stored in the database.
I have a table in a databases that contains 12 rows. I am loading a runtime dataset with that table. The result are displayed on 2 different controls. The first one is a DataRepeater and the second one is a DataGridView. The DataGridView displays all 12 rows just fine.
The DataRepeater does not. Some of the 12 rows will be blank and some will have the data. Sometimes I won't see any data until I completely cycle the scroll bar to the end and then back and still some of the 12 rows will be blank.
I have a data set that I am pulling from. I have no problem pulling dats into a text field but it doesn't sidplay in a drop dowl list.The Try witha text field brings back the dat without a hitch, but the Try with a ddl bring back nothing
I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):
I need to use an array at any part of the project. It has been suggested to me to build an array and show its result in a combobox. Instead of having an input textbox, i will have a combobox which will display 10 common names which are kept in the array.
'Defines the array Names Dim names(9) As String 'Defines the array's fields[code]......
the combox is bound database table,but it is not displaying the contents of table in database,instead it is displaying corresponding null values(blank).it is showing just "select" and the blank spaces corresponding to the number of items in database
here is my
Function combobfill() As DataSet addconnection.Open() Dim selectstring As String = "select materialsname from materialtype_table"
the code display 2 colunms in one combo box from a table. i have table with 2 columns account_type and account_name. the account_type is an abbreviation(codes) which would be stored in a new table when selected. I want the code when the combo is click, would display the code-account_type and account_name in the same combo box.
Private Sub cboAccount_type_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboAccount_type.SelectedIndexChanged Dim cn As New SqlConnection(ConnectionString) Dim query As String = "Select Concat(Account_type, ' - ', Account_Name) As AccountDesc, Account_type from Accounts"
I have a combobox that has filter items in it: Me.cmbFilter.DataSource = (From f In files _ Let extension = "*" & Path.GetExtension(f) _ Order By extension _ Select extension Distinct).ToArray() Displays OK in Vista - doesn't in XP
My DataGridView sorts by date. For grins I entered the date 11-02-2010 fully expecting it to be at the bottom of the list, not listed right after the last 11-02-2009 row and before the first 11-03-2009 row.How do I handle this so that come January 1, I won't see all the 01-01-2009 rows listed first followed by the 01-01-2010 rows then the 01-02-2009 rows, etc?
The Combo-box only has three items (Top View, From South looking North, From West looking East). Bound data from an Access Query called qryViewsFilteredByJob. I'm using it to pass a parameter to the filter for a binding source on a second query called qryAllSections2 (I don't think that's important though.)
When the form loads up it displays correctly stating on 'Top View', and I can click another other item just fine. When I pick another item, however, the first item, 'Top View', disappears and it replaced by whatever item I just clicked. So if I clicked 'From South looking North', the three item choices are now 'From South looking North', 'From West looking East', and 'From South looking North' again...
I have a problem with combobox. I set the DrawMode into OwnerDrawVariable so I can draw items seperately with styles, but the characters of the items are now displaying blocks. The block characters are none ASCII. It used to display well but not now and I don't know what caused it to happen. I didn't change my system locale. At the same time, other combobox that have Normal DrawMode displays nicely fine.
I am currently having a headache on how to solve this problem that i am facing.here is the situation:I have a combobox and a list box on the main form. The combobox will get the data from the ms access database.In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987
So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown.
I have a form with : 1. 1 Combobox with User1, User2, User3.....User10 2. 1 DataGridView with one column in Combobox columnstyle (with User1,User2,User3.....User10).
My problem is: I want to insert rows and the combobox for each row have to show the same user I set to the normal combobox.
Example: The normal combobox have "User1" as value....I want my new row have the "User1" selected and showed inside the columncombobox
The normal combobox have "User3" as value. Now I want the new row have the "User3" selected and showed inside the columncombobox. For now, if I change value in the combobox. My new row have the columncombobox value set to blank and if I click on it. I can see all the user inside.....
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.
I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
I have a datagridview that has 1 combobox column (it will eventually have between 1 and 3 more) but I can't find anything anywhere on how to add rows to this column. I create the columns:
I've populated my DataTable will all the results from a SQL search. Upon a button click I want to populate a combobox with all the results where a condition is met. My DataTable as a column called UserID and I want to add all results where the UserID is equal to a set value (for example 12). I can do this to add all results and I guess I could add a if statement inside this to be If Entry.Tag = 12 Then but is there a better way?
I am creating a program that will allow me to manage server EXE's for which I have the method to do so already completed. The problem comes when I want my front end to be able to use a database of different server configs stored in a dataset.
My Database has 4 columns (ServerID | ServerName | ServerPath | ServerMod)
I wish to be able to select the ServerName in a combo box (already done via Datasource/DataMember) and then load the ServerPATH and ServerMOD for that row into two variables.
I am Working VB.NET 08 Windows Appl.I Have Combobox and DataGridView in the Form.In the Combobx Having Names list Called "SurName".In The DataGridView on of the Column is "SurName".So when change the data on the Combobx list the dataGridView is Filtering and displaying the values correctly.For this i wrote a code in Select IndexChanged or SelectionCommitedChange Event.
But now my task is when i Type the text in the Combobox the related data should be filter in the DataGridView.If i type any letter in the Combbox the datagridview rows starts filter.
For Ex: Names are like 'Mali', 'Malu','Maal','Mouli'.
If i type 'M' letter in the Combobox then 4 rows Filter in the DataGridView. If i Type 'Ma' then 3 rows , If i type 'Mal' then 2 rows, If i type 'Mali' then 1 row.
I have a datagridview extracted from a csv file. It displays duplicate rows. How can I delete those duplicate rows from the datagridview? replies would be precious.
I am having issues when trying to populate a combobox that is dependent on another combobox. Populating the first combobox works as expected but attempting to set the value member or display member properties of the first combo box cause its selected index changed event to fire. That event seems to fire before the first combobox is fully loaded. The issue is then raised when trying to populate the second combo box, since it is dependent on having a valid value member to complete the dynamic sql statement, and at that point in time, there is no value member.
I can�t imagine that this is difficult but searching hasn�t yielded me any results. Should I be using a different event? What is the right way to do this?
I have a simple workaround in place - not allowing the second combo box to attempt to populate unless the first combobox has an index greater than zero but this hack is no good since it clearly prevents the user from selecting the first element in the first combo box.

All I am looking to do is display the current RAM usage being used in a textbox, nothing more nothing less. I will encorperate it into a timer and update automatically, how do I do this ?
I am querying a db based on some conditions and then I am putting these data in a text file. This is done by a for Loop. Is it possible to have some message box telling that data1 is being copied, data2 is being copied, etc. Some kind of dynamic textbox, telling what is being done at the background.
I've written some code to get an image file from a OpenFileDialog, and then offset the X position of the image by -50, and then display that offset image in a panel. But for some reason, it is displaying the image twice inside that panel. Could someone please tell me how to get it to only display the offset image in the panel? I'm sure it's something simple, but I'm wracking my brain with this one.
If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then Dim Bitmap As New Bitmap(OpenFileDialog1.FileName) Dim Graphic As Graphics = Graphics.FromImage(Bitmap)
I'm new to the world of VB.Net <-> Databases.I'm currently working on an application with SQL Compact 3.5.I realize that data et values on objects from the database but what I want is more custom...Students should have 3 fields for example, tableId, their name and birthYear.1 | John | 20002 | Peter | 1999And so on. What I want is to display their birthday on some label.text = "(" & DBvalue & ")" based on the selection of a listbox (which has tableId's listed as values). You don't have to worry about the update method of that label.text value, I just want a way to retrieve the birthYear value and put it into my label.text together with those extra characters, based on the tableId selected. (which I already have a way to get, so don't worry about that either).
I'm trying to make a way for them to export orders to a .rtf file. In order to preserve formatting (bold, underline, etc.), I'm creating a RichTextBox (through code) and formatting the text appropriately. To save the output, I'm simply using the RichTextBox.SaveFile method. Now, to list all of the products that were sold in the order, I'm deriving the information from a ListView. The ListView contains the product name, product price, and quantity sold of that product. I cannot find a way to list the output in a table-like structure, so I tried making a DataGridView and pasting it onto the RichTextBox. Unfortunately, this didn't work at all, so I was wondering if anyone had any ideas as to what I can do. I can't simply use Tabs to space out the information because it doesn't get formatted nicely.
