• Windows Forms Problem Copying Data From Column to Another Column in Datagrid

  Hi All, I have a datagrid and have created a button which copies the data from column 2 into column 3. Column 3 is a template column with a text box to allow manual data entry. Though when I copy the data from column 2 to column 3 the textbox is removed from column 3. This is the code I am using to copy the column data: private void cmd_UpdatePull_Click( object sender, System.EventArgs e) { foreach (DataGridItem dgi in DataGrid1.Items) { dgi.Cells[3].Text = dgi.Cells[2].Text; } } Any ideas how to fix this problem Rgds, Paul i assume you are using c#.

• Windows Forms Highlight the cell with an error...

  Hello everyone! I've got a DataGridView and when the user forgets to enter a value into a required field I would like that field to get focus when the error occours. Also if invalid data is entered I would like the invalid data to be marked (highlighted). Any ideas on how I could do this Right now I'm only showing a messagebox in the DataError event. Thanks in advance! -Martin Thank you, however I've got 4 cells in a row and they are all Required. If I enter value in the first one and then try to finish the row I get an error message in the first cell which has a value and should be valid. I did dgv[e.ColumnIndex, e.RowIndex].ErrorText = "Error!";. Any idea why =) ...Show All

• Visual C++ Simulating Left Mouse Button Click

  Hi, At the moment, I am running into a problem which is this: Every time I right-click on a TreeView item in my application, the selected item remains the item prior to right-clicking rather than changing to the right-clicked item. While this isn't exactly a BUG, it is quite an inconvenience. The most obvious solution to the problem, to me, is to simulate a left-button click in the right-click NM_RCLICK event that will in turn select the item prior to any further actions. Is there a better way to accomplish this If not, how can the left-click simulation be accomplished Thanks in advanced. ---Dan I'm running into a problem... I'm using straight Win32 SDK without MFC and am substituting some code...I am usi ...Show All

• Visual Studio System.Runtime.InteropServices.COMException (0x80041004): Not enough memory for operation.

  Hi there, I have CS2003 and Crystal Reports XI R2 standard edition installed on my machine. Before CR XI installed, my application and reports worked fine.

In that viewer im bringing up a report that pulls from the database fields that i imported to earlier. The report pulls up just fine and i can export the report to word, excell just fine, but it get a "Error Detected by export DLL" message when i try to export to a pdf.

• SQL Server could not find stored procedure 'dbo.sp_MSdropfkreferencingarticle'

  Hi, I'm trying to generate a snapshot of a database (running on SQL 2005 SP1) prior to starting transactional replication to an SQL 7.0 server. After generating the snapshot, the agent fails with the error message 'could not find stored procedure 'dbo.sp_MSdropfkreferencingarticle' and suggests lookin at error number 2812 (which offers no help). I was convinced this worked prior to installing SP1, but that testing was done some time ago.... Andy, this is a bug we need to fix (I am guessing you are using "truncate" as the pre-creation command). To workaround for now, you can: 1) Use drop as the pre-creation command 2) Create a dummy procedure "sp_MSdropfkreferencingarticle" at ...Show All

• Visual Studio SP1 ReportViewer: RenderingComplete event not firing if ReportViewer.Visible = false

  Hi all, In our product we use our own rendering progress screen, so when the RenderingBegin event fires we set the ReportViewer control Visible property to false so that our screen is visible. When the RenderingComplete event fires, we bring visibility back to the reportViewer control. The issue is that ever since installing SP1, the RenderingComplete event never fires if reportViewer.Visible = false. Has anyone else noticed this Thanks in advance, Jeremy Code snippet: private void _reportViewer_RenderingBegin(object sender, CancelEventArgs e) { this.ReportRendered = false; this._reportViewer.Visible = true; this._reportRenderInProgressCtrl.Visible = true; this._reportRenderInProgr ...Show All
