Radgrid issue with the shift key in multiselection

[Nicolas]

I wanted to know if there is a solution to a radgrid issue with the shift key in multiselection. When i do a multiselection of rows with shift key pressed, the radgrid doesn't throw a postback when the shift key is released.

I was testing some alternatives with the onkeyup event over radgrid but doesnt work well with shift key (dont throw event until ctrl key is pressed) , instead the event it works better with the ctrl key.

However i would appreciate a better solution that doesn't imply handling the key events.

I been follow this issue in this threads

Thanks in advance.

Hi Nicolas,

Note that multiselection using the Shift key is a client-side feature of the grid. It does no cause a postback and is used only for client selection. That is why it does not fire the ItemCommand event.
Handling such action on the server would require customizations through client script. You could use the RowSelected client event to capture the selections on the fireCommand() method to fire a custom command on the server and then handle it accordingly in the ItemCommand server event handler of the grid.

Thanks for the answer.
 I ask  If pressing ctrl key i'm throwing server side events, why the shift key couldnt do the same?

However i found a solution using the client key events.
When i push shift or ctrl then the attribute "enablepostbackonrowclick" is set to false.
Then when I release the keys the attribute "enablepostbackonrowclick" is set to true,
and throw the postback.

 For the moment the solution seem to serve. If errors are generated in the testing area I'm gonna try your aproach.

.

JS:
function onRadGridKeyDown(sender, eventArgs) {
if ((eventArgs.keyCode == 17 || eventArgs.keyCode == 16) &&
sender.control.ClientSettings.EnablePostBackOnRowClick) {
sender.control.ClientSettings.EnablePostBackOnRowClick =
false;
}
}
function onRadGridKeyUp(sender, eventArgs) {
if (eventArgs.keyCode == 17 || eventArgs.keyCode == 16) {
sender.control.ClientSettings.EnablePostBackOnRowClick =
true;
// if (sender.control.get_selectedItems().length > 0) {
__doPostBack(sender.control.UniqueID,
"select");
// }
}
}

ASPX.CS
   RGrid.Attributes.Add("onkeydown", "onRadGridKeyDown(this,event);");        
   RGrid.Attributes.Add("onkeyup", "onRadGridKeyUp(this,event);");
   RGrid.Attributes.Add("onmouseover", "this.focus();");
   RGrid..Attributes.Add("onFocus", "this.style.outline = '0px';");

 

 

Thanks again
