I'm loading the results of different stored procedures into a DGV.If the second time I load I have less columns - the DGV does not clear the extra ones.Seems if I do dgv.columns.clear I mess up the DGV in general
I've got this so far
'reportDGV.Columns.Clear()
'reportDGV.Rows.Clear()
reportDGV.DataSource = Nothing
reportDGV.DataSource = caseBAL_C.runReport(reportDrop.Text)
I'm doing this right now - .Add'ing parameters and then at the bottom I'm looping through them and setting the Source column by just removing the "@" character from the parameter name.

View 5 RepliesI have a gridview in asp.net using vb 2005. on " Protected Overrides Sub Render"some of the data in the columns gets modified. when i do a view source.. and look at a column1's values it says 0010. in the render i am taking a value of ab0010 and turning it into the 0010 that is seen in the view source.. later on, there is a button_click event that goes through each line of the gridview and grabs some values. Here I'm doing a CType(gvr.FindControl("column1"), Label).Text the value is coming back as ab0010. so the question is.. the view source shows something different than what is in the viewstate?
View 1 RepliesI have a very simple table in access. The data is stored from VB.NET using the OLEDB adapter. I have a second form which has just a single DataGridView which was dragged/dropped using VS2010 from the Data Sources window.When trying to view the window the first time no data is shown and the second time an exception occurs and the program closes.

In the Immediate window after clicking the Form.ShowDialog() button this message appears: A first chance exception of type 'System.ArgumentException' occurred in System.Data.dll Also, the data does not load into the datagridview. After closing the window and then clicking the same button (Not data has been changed at all) this error appears: Input string was not in a correct format.Couldn't store <07/11/2011 00:55:06> in Time Column. Expected type is Int32.
I'm trying to migrate (mostly mentally at this point) from MS Access to .NET for database programming. I've found one of the first tests to be fairly painful.

I have been working on an app that was basically a vb6 app but had to be changed and I did it all using VB 2008. works well, great. One of the problems that I had was to work on different groupboxes or frames. Since they are layered on top of each other, working on one frame would mess up the others. Eventually it all went okay. but now if i want to add another item in the menu and hence add another groupbox (or frame) in the same app - it would definitely be a nightmare.

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
