Accessing new value from Textbox in ItemTemplate/EditItemTemplate in RadGrid

[Hari krishna]

<telerik:GridTemplateColumn HeaderText="Amount" UniqueName="Amount" SortExpression="Amount" Aggregate="Custom" DataField="Amount">  

<ItemTemplate>
 <asp:TextBox runat="server" ID="txtAmount" Text='<%# Eval("Amount") %>' 

 DataFormatString="{0:C}" ></asp:TextBox> 

</ItemTemplate> 
 </telerik:GridTemplateColumn>

 

In the above code, initially, I used only ItemTemplate and added Textbox in it and tried to get the value entered by user in the ItemCommand event. But I couldn't get the new value from Textbox. It is giving the old value

I had used below code in the Itemcommand event to get the new value, but, didn't get the new value.

protected void grdPaymentHistory_OnItemCommand(object sender, GridCommandEventArgs e)

{ 

     var dataItem = e.Item as GridDataItem;

         var refundAmount = (TextBox)dataItem["Amount"].Controls[1];  

}

 

Later on, I thought that edited values may not be available in ItemTemplate. So, I used editItemTemplate which is containing textbox and validator.Now, when user clicks on edit button (GridEditcommandcolumn), textbox is avialable for entering the amount. I am trying to get the value entered by user in the textbox in the edititemtemplate. I am trying to get the value in ItemCommand event. Below is the Itemcommand event.

Here, I am getting the old value i.e the value which was there initially before the user edited.
 

<telerik:GridTemplateColumn HeaderText="Amount" UniqueName="Amount" SortExpression="Amount" Aggregate="Custom" DataField="Amount"> 

<ItemTemplate>  

<asp:Label runat="server" ID="lblAmount" Text='<%# Eval("Amount") %>'DataFormatString="{0:C}"></asp:Label>

 </ItemTemplate>

 <EditItemTemplate> 

<asp:TextBox runat="server" ID="txtAmount" Text='<%# Eval("Amount") %>' 

 DataFormatString="{0:C}" ></asp:TextBox>  

 

<asp:CustomValidator ID="RefundamountValidator" runat="server" ControlToValidate="txtAmount" 

OnServerValidate="RefundAmountValidation" ValidateEmptyText="True"  

ErrorMessage="Reassign To cannot be the same as Assigned To" SetFocusOnError="true" 

Text="*" Display="Dynamic" />  

 

</EditItemTemplate>

</telerik:GridTemplateColumn>

 

 

protected void grdPaymentHistory_OnItemCommand(object sender, GridCommandEventArgs e)

{ 

    foreach (GridDataItem item in grdPaymentHistory.EditItems)

        { 

        var TextBox1 = item.FindControl("txtAmount") as TextBox; 

        }
}


Please provide your valuable inputs to get the new value in both ItemTemplate and EditItemTemplate.
Thanks

Hi Jayesh,
               Thanks for the solution!! Acutally, on behalf of me, Hari had posted the above problem. Now, myself giving the reply.
                I had tried this as well, didn't work.

    GridEditableItem theItem = e.Item as GridEditableItem; 

    var amount = (TextBox)theItem.FindControl("txtAmount");
    
    I am not getting why it's not working.
