Database Is Selected And Displayed In A DataGridView?
May 11, 2009
I am using a DateTimePicker to allow the user to select dates between which, info from a database is selected and displayed in a DataGridView.This works fine exept that the dates selected by the DateTimePicker seem to bring back results in US date format!
If I do a debug.print (DateTime1.text), the date is in UK format i.e 11/05/2009 but when these variables are used in a Select statement, the dates returned seem to be in US format e.g. selecting dates between 01/04/2009 and 7/05/2009 selects dates between 04/01/2009 and 05/07/2009 when the results are displayed in the DataGridView!
I try to do a very simple job which is: Delete a row in dgv AND database! But now after three days I'm running out of steam
The problem is: I select on or more rows in dgv and push the del button. The sub zDelete starts working and at the end the selected row is gone and the row after my selection is gone too!?!? The deletion of the selected row was well done in dgv and database. But why is the next row in dgv only also disappeared??? After a restart of the form the missing row is back up again. And when I try to delete the last row it trows an exception error: System.IndexOutOfRangeException was unhandled
The code fragment is this:
'Delete all selected rows in dgv AND database! Private Sub zDelete() If MessageBox.Show("Do you really want to delete the selected rows?", "Delete", MessageBoxButtons.YesNo) = DialogResult.Yes Then
I am developing a Windows Forms Based Application using dbo.database and Visual Basic: I populate some Orders in DataGridView1 using LINQ 2 SQL from "tbl_Orders" where OrderStatus is "Pending". I change OrderStatus Column Type to "CheckBox" in DataGridView, Now I want that when I select some records (Orders) by checking respective checkboxes and click on "btn_UpdateStatus" Button, program pick OrderID's of only selected orders and update OrderStatus of Only selected Records (Orders) from "Pending" to "Completed" in Database Table "tbl_Orders" and DataGridView1 should be Refreshed. [code]
I want to see if anyone has used one table that has a primary key (not displayed) in the DataGridView. Then use a text box on the same form to call and group what if viewed in the DataGridView table. I want to group the displayed data of the DataGridView by the primary key of both tables.
I'm writing a program for my job in which we are keeping track of employees usage of food at work. The form in question interacts with an access database to a binded control with labels and textboxes. This form I'm working on is the user view which doesn't allow them to input their username, I have the user name saved to a variable but it will not display when I the add a new record. I tried many things but I'm just getting frustrated.
Is there away to add data to a row that is not displayed on the screen in a textbox for the user to see? There are 3 different "cells" (textboxes) I want to be filled in by other code without the users knowledge.
I'm currently using MSAccess 2010 and Visual Studio.net 2010
I have a datagridview with 3 displayed columns and 10 columns overall. If I run the program the gridview start with the first column visible and displayed. Now i want to scroll with the vertical scroll bar.
If i click on the "right" button of the scroll bar my DataGridView1.Scroll - event says: DataGridView1.Columns(0).Displayed=True DataGridView1.FirstDisplayedScrollingColumnIndex = 1
So this means "yes, the first Column is displayed but the first displayed Column is the second one!"
This doesn't make sense to me. Is there another opionion to this Problem, or is this just a small bug?
I use Visual Studio 2008 Pro (Visual Basic) with .NET Framework 3.5.
I am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.
I'm creating a Datagridview for user input. When the Datagridview shows on screen, the user can open a ContextMenuStrip that includes Copy, Cut, Insert, Delete, .[code]...
I made an account manager where i can store all my accounts and I want it more protected, how can I changed the displayed text in my "colPassword" in datagridview? Just like in textbox the PasswordChar, please give me sample code :)
I have a datagridview control on my form. i use this to display data including images. Please how can i set the row height of the datagridview control so the picture can be well displayed?
I have a number of records being displayed in a data grid view, but I want to be able to sort these records via the date. Clicking at the top of the column just sorts them in relation to the first number of the date.
I created a tree view and I would like to know if (and how) I can add to a given node a datatable (displayed in a datagridview) with a click on the same node. Let me know if my question is not well described.
I'm in the process of making 2 database applications. Each are encountering their own set of errors. For this particular application, I have a "Main Menu" form that has a button which loads an "Add Record" form. The user is suppose to be able to insert new records here via text boxes, but the problem is that record with the first primary key is being displayed in the text boxes when the "Add Record" form loads. I have no idea and can't find anything anywhere about making these boxes blank. I'm connecting to the .accdb through a dataset.
This is are the parts of my system where my problem occurs: - Search Button - List Box1 - TotalTextbox - Button - SQL Database with a Column named "Amount" and it only contains numbers Datatype is System.String
So, basically a user clicks the Search button and searches for a data in the SQL Database, and the result of the search displays in different Listboxes including the "Amount" Column from the database, which has it's own Listbox named "Listbox1". the Listbox is now filled with numbers.
Goal: The goal is to get the Sum of all the "Numbers" Displayed in the Listbox1, and the Total is then Displayed into a Textbox via using Click event or automatically.
The Code:
Dim sum As Double For x As Integer = 0 To ListBox1.Items.Count - 1 sum += CDbl(ListBox1.Items(x)) Next TotalTextBox.Text = sum.ToString
And i got this Error: Conversion from type 'DataRowView' to type 'Double' is not valid.
I ended up with this..
Dim sum As Double For x As Integer = 0 To ListBox1.Items.Count - 1 sum += Val(ListBox1.Items.Item(x).ToString) Next TotalTextBox.Text = sum.ToString
But the values are not adding up, the total is always at 0. i've been searching for hours now from the net to a better way of doing this.
Here's a quick Flow on what im trying to accomplish here. Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
I'm having a problem with my software. Im totally new to Vb.net and only learning through ebooks and google.This is are the parts of my system where my problem occurs:
I have to do some maintenance on an old VB.NET application (Visual Studio 2003) that uses Infragistics NetAdvantage 2006. I have a UltraCombo control binded to a DataView.
How can I refresh the content displayed after a change in the database?
I have an app that has been localized in the usual fashion (i.e., .resx files), which handles about 95% of the strings. However, I still need to localize some strings for category names that are stored in the database. I'd like to avoid adding 15 new columns named categoryname_ES, categoryname_FR, etc, and then pulling the right column dynamically. If there would be some way to pull the data, and then do a substitution in the code, I think that would be a little less messy. Maybe along the lines of:
go through gridview row by row if the language selected isn't English, look for this text value in a global resources file and replace it. Or is adding a lot of categoryname columns for each language just the way to go (ewww).
Using a Windows Form with a Menu bar and a Gridview control, I have bound data to the GridView from an MS Access 2000 database query using Dataset. The contents of this table displays just fine. But I want to be able for the user to select a different query from the menu bar and display it in the same GridView control. How can I change the query bound to the control (in VB)?
Public Class Actinide Private Sub Minerals_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Actinide_Series__Radioactive_TableAdapter.Fill(Me.Minerals2000DataSet._Actinide_Series__Radioactive_) End Sub Private Sub LanthanideToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LanthanideToolStri
[code]....
The error message that it is giving me is:
"Value of type 'Mineralogy.Minerals2000DataSet.Yttrium_MineralsDa ta Table cannot be converted to 'Mineralogy.Minerals2000DataSet._Actinide_Series__ Radioactive_Data Table'.
The query is getting information from two seperate tables,so I can't just bind a table to the control and then filter what is displayed using SQL.
I've created a Gridview control that pulls some data from my database, but doesn't display all of the information I'm hoping it gathers. I choose not to display the primary key for user interface purposes, but require that key for basic operations on the grid.I'm currently attempting to add a "Delete" option to the table, but unfortunately I'm having very little luck. Here's my .aspx file.
When a user clicks the + button on the binding navigator, I want to set the displayed item of acombobox to the value displayed in a label. The combobox is bound to a field in the table. Theproblemis that when the user clicks to add a new record the combobox is cleared and they forget to select a value before they click save.
I am working on getting a multiple values from a single column displayed in a single textbox or label. I know I should be able to find the information I need online, but I am coming up empty. I am using Visual Studio 2010 with SQL Server 2005. For example, I want to pull all the email addresses, that have a value, from a table and display them together. The output I am looking for is like this:
I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.
