Hello,


You can check for whether the Selected property of GridDataItem is "True" or "False" instead of accessing the CheckBox control and checking the Checked property.

Hello,

I hope the sample code shown below will help you to get started.

CS:

protected void Button1_Click(object sender, EventArgs e)
{
    GridDataItem firstItem = (GridDataItem)RadGrid1.MasterTableView.Items[0]; // Get the first DataItem
    if (firstItem.Selected) // Check for whether it is selected (checked) or not
    {
        Response.Write("Selected");
    }
    else
    {
        Response.Write("Not selected");
    }
}

Also go through the following documentation:
Retrieving primary key field values for selected items

I am finding that this only works on the first row. I have a textbox. If the clientcheckcolumn checkbox is checked, it copies a value from one column into the textbox. However, on the TextChanged server-side code, if the textbox values is changed, then I want the checkbox to uncheck.

How to programatically uncheck the checkbox if the textbox value changes? I have used the code from this example but it only works once.

What is the correct way to reference the checkbox checked property. I do not want to loop through every row, just find the checkbox.checked for the row that has had the textbox edited.

protected void AmountApproved_TextChanged(object sender, EventArgs e)
    {

        GridDataItem firstItem = (GridDataItem)gridFundingBills.MasterTableView.Items[0]; // Get the first DataItem
        if (firstItem.Selected) // Check for whether it is selected (checked) or not
        {
            firstItem.Selected = false;
        }
        else
        {
            Response.Write("Not selected");
        }


        UpdateBalances();
       
    }

Hello Thomas,

You can get a reference to the row using (sender as TextBox).NamingContainer as GridDataItem.
Then, you can toggle the selection of the item depending on your custom condition or find any given template control using the FindControl method.

Hope this helps. You can also achieve that on client-side.

This is a little vague. I am trying to access the checked state of a gridclientselectcolumn in the TextChanged event:

<telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="50px" ItemStyle-Width="50px">
                        </telerik:GridClientSelectColumn> 


protected void AmountApproved_TextChanged(object sender, EventArgs e)
    {
     //Some text has changed, now I want to see if the ClientSelectColumn checkbox is checked
     //what is the syntax?
     if (thereIsAColumnWithAuniqueNameOfClientSelectColumn.checked == true)
          {
              thereIsAColumnWithAuniqueNameOfClientSelectColumn.checked   = false;
         }
}

Hello Thomas,

The correct way for handling this would be to get reference to the parent GridDataItem (using the NamingContainer property of your TextBox control) and check its Selected property. If it is set to true, this
will mean that the item is selected.

Generally, as the name clearly stated, this is a GridClientSelectColumn and you should not use that column for retrieving the selected state of an item.

You can take a look at the following help article for accessing controls in RadGrid:

• Accessing Cells and Rows

Hi,


I am using a GridClientSelectColumn and have a paging on my grid. I need following things on my grid.


1) Multiple selection client-side
2) If do select all from the header checkbox on page1, it should also select the rows at all other pages.
3) Deselect should deselect only the single row, not all.
4) If select a single row on and move on to any other page and now when come back to page1 the row should persist its state.


I would appreciate any help on this.

Thanks, 

Rahul

Hello Rahul,

You can use the following approach to preserve selection through pages:
https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/how-to/Selecting/persisting-selected-rows-client-side

You can examine the RadGridGetAllSelectedItemsImproved.zip web site sample provided in the last post here for a practical implementation:
http://www.telerik.com/support/code-library/get-selected-items-through-all-pages#1eTU8nr-GUG8zfGgOGbIcA

I hope this will prove helpful.
