I have a datagridview that I am dynamically building columns for, adding them to the datagridview, and then attaching a dataset. The dataset has more than one table. What sort of syntax should I use to specify the datatable column that the DataGridViewColumn needs to look for in the dataset
View 4 RepliesI created a custom datagridview column for a progressbar and included customizable color properties but I can't get them to work right. After compiling, the properties show up correctly in the Edit Columns popup editor, but changing the values has no effectThe designer generated code shows the original values and manually changing them there has the desired effect(I know you're not supposed to, just testing). Here is the code for the column even though I don't think the issue is stemming from any coding errors there.
Imports System.Drawing
Imports System.ComponentModel
Imports System.Drawing.Drawing2D

I have noticed that when iterating DataGridViewColumns, the speed is greatly reduced if the columns are visible.
For Each col As DataGridViewColumn In cData.DataGridView.Columns
col.Visible = visible
Next
If visible is set to false (and all columns are all currently visible), iterating 264 columns takes around 0.35s, however, if visible is set to true (and all columns are currently invisible), the same process takes around 30s.Does anyone know what would be causing the extra time?Could it something internal to the DataGridView Control?
I use VB 2008,I need to create DateTime DataGridview Column..how create Custom DataGridview Column with using DateTimePicker
View 3 RepliesI created a custom datagridview. In the constructor of that datagridview, I set
Me.AutoGenerateColumns = False
and then, declared and added 4 DatagridViewImageColumns and 140
DatagridViewTextBoxColumns by the code

Dim dvgCol as New DataGridViewImageColumn

But when I add an instance of that datagridview onto a form, in the form.design.vb there are many code defines for each columns and then sometimes adds additional code to create those columns again. Sometime when I delete the datagridview control in the form,that code is not deleted.
I am building an application that contains several DataGridViews that may have 100-20,000 rows displayed with a DataTable as its DataSource.When the user wants to filter a column they right-click the DataGridView Column Header and a ContextMenuStrip shows a small DataGridView that displays all the unique values in that column. I currently get all the unique values using a loop which is slow (shown below).[code]...
View 3 RepliesIs there a way to find the column index of a datagridview column using the columns DataPropertyName?I currently use a loop (shown below in the class) which is kind of ugly, but it works. I'd like to do something like this, which seems more elegant.My goal is this, I store the users DataGridView column settings (i.e. DisplayIndex, Visible, & Width).When the user opens the form that contains the datagridview I want to get those settings from the database and apply the settings to the datagridview.[code]
View 5 RepliesI am working with a datagridview. Is there any chance a column is set to be a textbox initially but for example I want the top item to be a combobox??? This should enabled the user to select something of the list but also load in what was selected and saved before... So for example I have a column called Product Name and it has 5 rows 4 of them should appear as textboxes but one top cell should appear as combobox

My problem is that I want to know if an instance of my application is already running and, in that case, I want to jump directly to that instance, without starting another one.

Under Tools->Options->Debugging, Edit and Continue are already selected; so it's something else. Also, under project properties->compile I have it set to Cofiguration (Active Debug) and Platform (Active Any CPU).

Now i want to make a setup of this project but i am unable to integrate sqldatabase and .net framework in this setup project. Is there any way to do this. Because it is assumed that the client does not have .NET Framework installed nor he has SQL Server on his system and the worst condition would be he does not have even internet connection from where these two setups can be downloaded if we give the condition for downloading these programs from the net if the client does not have these programs installed on his machine.
View 2 RepliesI'm attempting to copy a rather complex form from one part of my project and use it (modified) within another part (ie, depending on whether it's maintenance or an outage, you'll get a slightly different email screen).
My first attempt failed miserably, as I had simply right-clicked and pasted the form within the project, assuming renaming the controls would work. nope, I didn't realise that there was stuff in the original form that was renamed as well, and that created a monstrous pile of errors.My second through fourth attempts also failed, generating errors in forms that (I thought) weren't related or connected. Once I deleted the copied form, all was fine.
So, short of trying to rebuild the form from scratch (using a different naming convention for my controls etc.), is there a simple way of doing this? This seems to be such a simple task, but alas I was wrong....(or, at least it's not easy with the information I have right now.
