VS 2008 Dynamically Creating And Adding A ComboBox To A Specified Column In DGV?
Mar 19, 2012
I am dynamically creating and adding a ComboBox to a specified column in DGV. I also set a DataSource, DisplayMember and ValueMember for the created ComboBox. Somewhere else in my program, I select a number ( let's say 5 ) and based on that number I want to change the SelectedIndex of the current ComboBoxColumn ( I actually loop through the Columns collection ).I tried something like this in a event handler I created:
vb.net
Private Sub combobox_validated(ByVal sender As Object, ByVal e As System.EventArgs)
Dim combobox As System.Windows.Forms.ComboBox = sender
Dim colIndex As Integer = combobox.Tag
[code]....
You will notice here, that I'm not actually trying to change the .SelectedIndex property, but the Value of the current cell.How do I reference the actual ComboBox?
I am dynamically creating and adding dropdown controls to DevExpress XtraGrid.That works fine and I can add a dropdown control to any column I wish.My main problem is that I need to have the first element in the dropdown control displayed. But after I dynamically add 3 dropdown controls to the grid, only the last one has the element displayed. The previous two do not.Although, I add the elements
this is what the code looks like:
vb.net Dim column as DevExpress.XtraGrid.RepositoryItem.GridLookupEdit For i as Integer = 0 to dsSometing.Tables(0).Rows.Count - 1 column = New DevExpress.XtraGrid.RepositoryItem.GridLookUp
[code]....
The code will go tru and add lets say 3 dropdown controls, set their .DataSource to datasets I need, but it will only show .NullText of the last added control.
in order to create my own type of columns. USERNAME to have type ComboBox NAME to be type normal like it comes from dataset But I don't know how to create a a column that is combobox and another one that is normal like it comes from dataset.
actually i have 3 fields in database which are Sid Fee status what i want to add combo column in field [status] with two option PAID or UNPAID which a user can select and update it .i am all clear with filling the datagridview from database and updating but only problem is adding a combobox in third field that is status.
i tried it with this Dim combo As DataGridViewComboBoxColumn DataGridView1.Columns("combo")
I am using a DataBindingSource to connect a DataTable to a DataGridView. Everything was working fine until I added a ComboBoxColumn
Dim ReasonColumnIndex As Integer = dgvData.Columns("Reason").Index Dim ReasonCombo As New DataGridViewComboBoxColumn With ReasonCombo .Name = "Reason" .Items.Add("BREAK")
I'm making a LAN instant messenger and I'm trying to achieve something similar to how MSN will open a new chatting window when you double click on a friend. My main form has a list of friends, and I want to create a new chat window when they double click on one of those friends. I've created a "template" chat form which I want to generate dynamically, and I've run into some problems I need help with. Lets look at the code I already have.
[Code]...
Now, call me a newb if you will, but I really don't know much about threading and all that hocus pocus. Some guidance in the right direction would be great.
EDIT: ClientWind is the chat form.EDIT: That's weird. It doesn't occur with the actual builds.
I am using CompilerParameters to dynamically compile code... The problem is when I use: cp.ReferencedAssemblies.Add(CompilerPath & "est.exe") to add a reference to test exe ... (where CompilerPath is the full path name) Compiler Path is not the Compiler Application Path
I get an error when compiling stating that: vb "Could not load file or assembly 'test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." If I put it in the test.dll in the "compiler apps" path and then call ReferencedAssemblies.Add with the full path it works.
Code: Public Class Form1 Dim NPB As Button Dim x As Integer
[code]....
As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?
I'm trying to read the records into a combobox from the database without any success. There is no problem with the connection, but something seems wrong with my coding. Perhaps someone could tell me what I'm doing wrong.
i am trying to count up to a number and add each number to a combo box. so for instance, the string value = 7. i want the combobox to count up to 7 in single numbers starting with 1
I am working on a program where the user inputs values, then the program calculates those values and outputs the sum. When the user hits the button exit then those values entered by the user are saved. When the user starts the program again, the values are still there. I wrote the code and everything works fine. I am saving those values in notepad... and the program grabs the input in notepad and outputs those values to the program. But here comes the problem: Lets say the user wants the information in a certain column to be added to another column somewhere in the program. Is that possible ? And if it is can it be done when I am saving those values in notepad?
I just want to ask the following infor from you in relation to gridview... I have 3 Grids, Grid A Grid B Grid C
Grid a has already a data but aside from the data in my grid A I want to add another column for a checkBox. Next, when the checkbox is check and I hit the button "Transfer" the row in the grid in where the additional column checkbox has been check will be transfer to grid B and the remaining data will be move to Grid C?
I am using this to populate column1 combobox from a text file and it works fine.[code]I tried to add a number range using this to populate columns 4 and 5..[code]The number range populates the combobox(CB) fine but when i select a number from the CB it causes a error and selects the first item, the error loops evertime the mouse hovers over the CB..[code]
I'm currently trying to add all the sections of a specified .ini into a combobox.[code]Now that's my section in the .ini, but it's scrambled and placed into multiple lines. I just want it on a single line as said in the .ini.Does anyone have any idea how to get values between brackets "[hi]" and place the value between the brackets into the combobox items?
I am trying to add some style properties to a column but the code I am currently using doesnt seem to work at all? Dim oApp As New Excel.Application Dim oWB As Excel.Workbook = oApp.Workbooks.Add() Dim oWS As Excel.Worksheet = CType(oWB.Worksheets(1), Excel.Worksheet) Dim style As Microsoft.Office.Interop.Excel.Style style = oWB.Styles.Add("Style1") [Code] ..... It's still the same as "default" would look when just opening up excel for the first time.
I have a datagridview and a bindingsource. The first column is a comboboxcolumn which is bound to a table field and then the rest of the items are populated from another datatable. What I have on my other forms is a textbox called txtfilter and on the textchanged event I have this
Me.ProductBindingSource.Filter = "BatchNo LIKE '" & txtFilter.Text & "*'" that works great. Now I want to filter the combobox columns just like this.
Problem: Calling a method which uses a cell's value from a DataBound DataGridView. Works as desired without adding an image column.When I add the image column, the method attempts to use the value from column 1 instead of column 2, as the code in the 2nd method below ("findSign") states:
I have this test form where I'm testing the idea, but ran into a snag. Now the main idea is to load all the data from a dataset into the one column of the datagridview. This works perfectly as shown in the image. Now there is something that I want to happen, but just can't get it right. when on the DataGridViewComboBox Column I also want to be able to type in my own data if the one I want is not available in the combobox.
Also if there are 50 values in my combobox and 2 of them are: jacky, jacson When I type jac, I want the combobox to only give me the options starting with "jac"
Here is the code that I'm currently using: Dim dt As DataTable Dim dsNewDataset As New DataSet() Dim i = 0, intSetArray As Integer = 0 Public Function JT_PullDataWithCOLUMNS1(ByVal Cols As String, ByVal TableName As String) As DataTable [Code] .....
I have a table adaptor that pulls from the sql database, when I edit the table adaptor query it makes this specific table adaptor not a part of the dataset. I have added a column to my database which will contain an integer, when I try to add this column to the query this error occurs, i am using the configure area of the table adaptor. Error 'AuditProductsTableAdapter' is not a member of 'MemKingClient.MemKingDataSetTableAdapters.TableAdapterManager'.
I wanted to make an executable file from my program. I already know that compiling your project creates an executable, but I wanted to know how to make an exe with my program.

I am working on a simple windows app that will take our TripleDESCryptoServiceProvider Key and IV from a file and use it to Encrypt and Decrypt strings, etc...This works great and has for years in a utility program, but I want an easy app that can read the Key and IV...following format in the txt file:
And then create the Encryption Pair...Currently I have the following
clientDESCryptoServiceProvider = New _ TripleDESCryptoServiceProvider clientDESCryptoServiceProvider.Key = New Byte() {111, 222, 333,...} clientDESCryptoServiceProvider.IV = New Byte() {1,2,3,...}
Is there any way to pull the {111,222,333,...} and {1,2,3,...} from a text file and create the Byte() that is required?I can read the info from the text file, but cannot seem to create the right format for generating the Byte()?
