Hello,

Try the following code snippet to loop  through the Selected rows in a Grid. Set the required key field as the DataKeyName.

aspx:

<MasterTableView  DataKeyNames="EmployeeID"  >

C#:

foreach (GridDataItem item in RadGrid1.SelectedItems)
 {
           string strKey = item.GetDataKeyValue("EmployeeID").ToString();
 }

Note: You can try the following approach to persist the selected row after postback.
Persisting the selected rows on sorting/paging/filtering/grouping

Thanks,

Hello Trunghieu,

The OnRowSelected client side event fires when a row is selected in grid. Attach the 'OnRowSelected' and handle the event.

and i have a question,how to get value in textbox (txtsl) in radgrid
Thank !

Hello,

Since the TextBox is inside the ItemTemplate, you cannot access the it directly.
Try the following client side code to enable the TextBox from client side OnRowSelected event.
Javascript:

function OnRowSelected(sender, args)
   {
       args.get_gridDataItem(args.get_itemIndexHierarchical()).findElement("txtsl").disabled = false;
   }

Thanks,
Shinu.

Hello Trunghieu,

I am not sure about the issue you are facing. Here am pasting the full code I tried. Please check it with your code and let me know if you need any further assistance.
aspx:

<telerik:RadGrid   EnableEmbeddedSkins="true"  ID="rad" runat="server" Width="600px" DataSourceID="SqlDataSource1"
            AutoGenerateEditColumn="true" >
            <MasterTableView DataKeyNames="EmployeeID" AllowPaging="true" EditMode="EditForms">
                <Columns>
                    <telerik:GridBoundColumn DataField="EmployeeID" Aggregate="Count" HeaderText="EmployeeID"
                        UniqueName="EmployeeID">
                    </telerik:GridBoundColumn>
                    <telerik:GridTemplateColumn UniqueName="TemplateColumn1">
                        <ItemTemplate>
                            <asp:TextBox ID="txt1" runat="server" Enabled="false">
                            </asp:TextBox>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>
                </Columns>
            </MasterTableView>
            <ClientSettings  ClientEvents-OnRowSelected="OnRowSelected">
                <Selecting AllowRowSelect="true" />
            </ClientSettings>
</telerik:RadGrid>

Javascript:

<script type="text/javascript">
    function OnRowSelected(sender, args)
    {
        args.get_gridDataItem(args.get_itemIndexHierarchical()).findElement("txt1").disabled = false;
    }
</script>

Hello Trunghieu,

You can access the selected row items as shown below.
C#:

foreach(GridDataItem item in RadGrid1.SelectedItems)//loops through selected row
   {
      String s= item["ColumnUniqueName"].Text;
   }

Also take a look at the following documentation.
Accessing cells and rows.

Thanks,
Shinu.

[trunghieu]

Thank ! but i don't using column unique, i using RadGrid1.datasource = datatable,how to get unique column ?

[Shinu]

Hello Trunghieu,

Give a try with the following approach.

C#:

foreach(GridDataItem item in RadGrid1.SelectedItems)//loops through selected row

{

   foreach (GridColumn col in RadGrid1.MasterTableView.Columns)

            {

                item[col.UniqueName].Text

            }

}


Thanks,
Shinu.

[trunghieu]

Thank Shiru,but i want to get exactly column 3 and 5,what should i do ??

Thank !

[Shinu]

Hello Trunghieu,

Try the following approach to get the columns 3 and 5.

C#:

int count = 0;

foreach (GridColumn col in RadGrid2.MasterTableView.Columns)

 {

   if (count == 3 || count == 5)

     {

       item[col.UniqueName].Text = "hhhhhhhhh"; 


     }
      count++;//Increments the count


 }


Thanks,
Shinu.


[trunghieu]

Thank Shiru , but i think your code not run because count=3 or 5  count++,but frist count=0 so count never = 3

Thank !

[Shinu]

Hi ,

Sorry for the mistake. I have edited the code.

Hope it helps you.

Thanks,
Shinu.
