RadGrid CheckBox Selection

[john]

Hi,

   I am using RadGrid ,an d i have given ClientselectColumn for multiselect.
From the server side am using following code

string

 

script = string.Empty;

 

 

script = script +

"selected = new Array();";

 

 

 

foreach (int id in lstselectedIDS)

 

 

{

 

script = script +

"selected.push(\"" + id + "\");";

 

 

}

 

script +=

"SetSelectedRowCount();";

 

 

 

base.AddStartupScript(script);

from the client side am taking the elements in the selected array and making the selection in Rowcreated event  like this

 

 

function

 

Grid_RowCreated(sender, args) {

 

 

 

 

var _Id = args.getDataKeyValue(sender.get_masterTableView().get_name());

 

 

 

 

if (selected.contains(_Id)) {

 

 

args.get_gridDataItem().set_selected(

 

true);

 

 

}
}

Because of this when ever i click on Check box for deselecting it is happening correctly. But if i click again for selecting it it is not happening properly. I need click checkbox 2 times for making a selection.

This is happening only for the selected rows.

If i use server side selection in ItemdataBoud Event, am not getting this problem.
Like
e.Item.Selected=true;
But i need to use the former one

And also am facing this problem in  many screens,please help me by giving the solution as soon as possible.


Thanks,
John

Hello John,

Please try using the selectItem client-side method in order to select the item and let me know whether it helps.

All the best,

Hi John,

Try this.
From the client side,When ever if u click first time on check box try to capture the selectedindexes.

I think it might storing duplicate indexes.
For example 2 rows are selected in the grid. Check that selectedindexes contains (0,0,1,1) instead of (0,1).
U can remove that many on first time deselecting.


Thanks,
Badri

Hello,

Could you please send us the complete code you use for storing the selected indexes and for retrieving them?
We will examine it and get back to you with our findings.

Additionally, you can review the following code libraries in which similar functionality is implemented:
Selecting/Deselecting rows on clicking row itself and without interfering selected items
RadGrid client side toggle selection with server side persisting of the selected items after Sorting, Filtering and Paging

I hope this helps.

Best wishes,
