Hi Telerik,

Do you guys have a work around for this issue?

When I try to use the following code the column widths get all messed up.

 private void BuildGridColumns()  
        {  
            grdrResults.MasterGridViewTemplate.AutoGenerateColumns = false;  
            grdrResults.MasterGridViewTemplate.AllowAutoSizeColumns = true;  
            grdrResults.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("DocID"));  
            grdrResults.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("DocName"));  
            grdrResults.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("DocTypeName"));  
            grdrResults.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("DocCatName"));  
            grdrResults.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("DocStatusName"));  
        }  
 
        private void BindData(string strCatName, int intStateID)  
        {  
            grdrResults.MasterGridViewTemplate.Columns.Clear();  
            BuildGridColumns();  
            grdrResults.DataSource = AppDocument.SearchDocuments("ReturnAll", 0, 0, "", 0, strCatName, 0, "Released", "", 0, intStateID, 0, false);  
        } 

Regards,
Mike

Hello mike,

Thank you for reporting this issue.

We managed to reproduce it. It will be addressed in our upcoming release Q1 2008. To work around this issue, place a call to the BeginUpdate method before clearing the columns and a call to the EndUpdate method after binding the grid. Refer to the code snippet below:

private void BindData(string strCatName, int intStateID) 
    grdrResults.GridElement.BeginUpdate(); 
    grdrResults.MasterGridViewTemplate.Columns.Clear(); 
    BuildGridColumns(); 
    grdrResults.DataSource = AppDocument.SearchDocuments("ReturnAll", 0, 0, "", 0, strCatName, 0, "Released""", 0, intStateID, 0, false); 
    grdrResults.GridElement.EndUpdate(); 
}  
 

I hope this helps. Let me know, if you need further assistance.

Sincerely yours,
Jack

Hello,

To clear selection in the current version you can use:
VB:
Me.RadGridView1.ClearSelection()
Me.RadGridView1.CurrentRow = Nothing
'usually this is enough but if you still have something selected you should uncomment the following line
'Me.RadGridView1.CurrentCell.IsSelected = False

C#:
this.radGridView1.ClearSelection();
this.radGridView1.CurrentRow = null;
//usually this is enough but if you still have something selected you should uncomment the following line
this.radGridView1.CurrentCell.IsSelected = false;

Hope this helps, if you have any other questions or comments, please let me know,

Best Regards,
Emanuel Varga

Hi Jose,

Regarding the Rows.Clear method, it works only when using a data source that supports it or when RadGridView is used in unbound mode.

Regarding the layout issue, I tested the case using our latest release and it works well. Please contact us if you experience issues. We will be glad to help.

Should you have any other questions, do not hesitate to write us.

Good morning!

My version of the telerik is RadControls for ASP.NET Ajax 2010 Q3.

I'm trying to remove columns that are inserted with the command gridProntuarios.MasterTableView.Columns.Add() of grid through the command "gridProntuarios.MasterTableView.Columns.Clear();" and
"gridProntuarios.Columns.Clear();" but don't work.

What would the solution for this trouble?

Thanks!

Hello,

You have posted your question in the WinForms forums. To gain a quicker, more accurate response, please re-direct your question to the asp.net ajax forums where I'm sure you will find the help that you need. May I also request that you only post your questions once as posting multiple questions that are the same may further slow down response times.

Regards,
Richard
