Hi...

In grid View Control while adding the rows some time it passing row index value as -1.i saw what is the reason and i found it.

1)First time Grid shows click here to add new row.so we click the row and adding values continuously.in the last column we press tab or enter ,it adds new row and adding values that time if any event occur,row index is passing as -1.
2) reason is , if grid shows Click here to add new row ,the grid passes row index correctly.or else it passes -1.

Please help me...is there any way to avoid this?

Child cell element not theming.

I have a a derived version of GridViewMultiComboBoxColumn, which is exposing a default editor type that is a CustomRadMultiColumnComboBoxElement (derived from RadMultiColumnComboBoxElement). The derived class is overriding ThemeEffectiveType and returning RadMultiColumnComboBoxElement, however, it's not themed when it moves into edit mode. How do I get it to theme properly?

An image of what I'm talking about is here:

The button is gray, but should be blue to match with the rest of the UI. Also, the textbox shouldn't have the border around it like it does. How do I fix this issue?

Checkbox in Header

Hi, i tried to follow this KB "how to add a checkbox header" to add a checkbox to the header of a checkboxcolumn but is not working at all. i'm using dll 2010.2.10.610. I think the problem is when the execution get to this method:

public override Type GetCellType(GridViewRowInfo row)

{

if (row is GridViewTableHeaderRowInfo)

{

return typeof(CheckBoxHeaderCell);

}

return base.GetCellType(row);

}

the row is never of the type GridViewTableHeaderRowInfo always is a gridviewdatarowinfo.

How i can solve this??

Hierarchical RadGridView performance

Hello,
I experience poor performance in hierarchical RadGridView which is bounded to BindingSource object.

Using bindingSource.ResetBindings(false) in this grid lasts almost 2 seconds (in normal grid it lasts only 0,1sec).
Relation is created in designer (not programmatically). There are 5k rows in BindingSource. Grid is bounded to BindingSource in designer (radGridView.DataSource = bindingSource);

Can you give any clues how can I make bindingSource.ResetBindings() faster ?

Show menu when button clicked on chart serie item.

Hello!

Is there any possibility to get information about button clicked on chart item, because I need to show context menu if right button clicked.

For know I use following code:

private void ActiveRegion_Click(object sender, RegionClickEventArgs args)

{

var fileId = Convert.ToInt32(args.Element.ActiveRegion.Attributes);

_tableFilesBindingSource.Position = SearchFilesTableBindingSource(fileId);

_isOnSomeSerieItem = true;

}

...

private void _radChart1_MouseClick(object sender, MouseEventArgs e)

{

if (e.Button == MouseButtons.Right && _isOnSomeSerie)

{

GetFileGridMenu().Show(_radChart1, e.X, e.Y);

_isOnSomeSerieItem = false;

}

where _isSomeSerieItem is private filed.
Is there more correct way to do that?

“Folder Tree” cannot retrieve data correctly.

“Folder Tree” mode.
Private Sub Grid_CellBeginEdit(ByVal sender As Object, ByVal e As GridViewCellCancelEventArgs)
programName = DirectCast(Grid.Rows(e.RowIndex).Cells("program").Value, String)

with code in your example, i could not get the correct cell value because e.rowindex somehow is the wrong row... due to rearranging in tree mode...

It took me few hours to find out that your e.rowindex is reference to the non-tree mode grid... so how can I get user interaction during the tree mode?

Also your support ticket page is 404 error.

Thanks,
J.
