[Solved] set_selected speed problem

[Francisco]

Hello

I'm using set_selected() to select many rows from a RadGrid in a loop similar to this:

mtv = grid.get_masterTableView();

dataItems = mtv.get_dataItems();

for (z; z < AllAvailablePipes; z++) {

    dataItem = dataItems[z];

    var item = dataItem.set_selected(true);

    SelectedPipes = SelectedPipes + 1

    if (SelectedPipes == PipesToBeSelected) break

}

Telerik.Web.UI assembly version is 2011.1.519.40

The problem is the speed. It takes about 5 to 10 seconds for this to run for about 80 rows. In some old slow computers where I need this to run, it takes more than 25 seconds!!!

The grid has a column GridClientSelectColumn:

 

<telerik:GridClientSelectColumn ConfirmDialogType="RadWindow" UniqueName="ClientSelectColumn">
     <HeaderStyle Width="50px" /> 
</telerik:GridClientSelectColumn>

 

Removing that column reduces the time by half. But that is still too much and I need that column. ClientEvents like OnRowSelected or OnRowSelecting are not used at all.

Any suggestion?

Thanks, Francisco.
