Update Grid's control from Popup window

[Mukesh]

Hi,

I am using Radgrid with inline editing... and on clicking on a button inside edited row, I am opening a popup window.

The Popup window has a textbox and a submit button.

Now when I click on submit button from popup, i want to update the textbox value to parent page (inside radgrid edited row).


For more details please have a look on attached screenshot




Thanks
Mukesh

Hello,


Here is one suggestion to achieve this:

• Access the button control in editform, also get the textbox value in ItemDataBound event.
• Now attach the "onclick" to button by passing the textbox value.
• In the client side event handler, open the window using any f the methods in documentation.
• Pass the textbox value as url query string when creating url.
• In the pageload event of RadWindow page, get the url parameter and populate the textbox.

Hi Shinu,

Thanks for your promt reply, but this can't solve my problem, because I don't have to refresh the parent page.
If i refresh the parent page the grid's edit mode will be disappear.


Thanks

Hi Shinu,

I am using Grid's inline editing, and I am able to get textbox of grid for existing rows by following code:               

                var grid = $find("<%=grdRouting.ClientID %>"); 
                var MasterTable = grid.get_masterTableView(); 
                var textbox = MasterTable.get_dataItems()[index].findElement("txtUserValue");

But I am unable to get the textbox of newly added row. because its not the part of MasterTable.get_dataItems()

So, how can I access the textbox of newly added row.


Thanks

Hello Mukesh,

You can try the following approach to achieve your requirement.

• Open the Radwindow in OnClientClick event of Button(which is inside ItemTemplate of RadGrid).
• In ItemCreated event save the ClientID of TextBox (which is inside ItemTemplate of RadGrid) in a HiddenField.
• Then attach an 'onclick' event to the 'Submit' button(which is inside RadWindow) from code behind and pass the ClientID of the TextBox(inside RadWindow) to the event handler.
• In that 'onclick' event handler access the TextBox inside ItemTemplate using the HiddenField.


ASPX:

<telerik:RadWindow ID="RadWindow2" runat="server">
    <ContentTemplate>
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:Button ID="Button2" runat="server" Text="Submit" />
    </ContentTemplate>
</telerik:RadWindow>

<telerik:RadGrid . . . . . . .>
. . . . . . . .
<Columns>
    <telerik:GridTemplateColumn>
        <ItemTemplate>
            <asp:TextBox ID="TextBox1" runat="server" ></asp:TextBox>
        </ItemTemplate>
    </telerik:GridTemplateColumn>
    <telerik:GridTemplateColumn>
        <ItemTemplate>
            <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return openWindow();" />
        </ItemTemplate>
    </telerik:GridTemplateColumn>
</Columns>
. .  . . . . .
</telerik:RadGrid>

<asp:HiddenField ID="HiddenField1" runat="server" />

Java Script:

<script type="text/javascript">
   function openWindow() // to open RadWindow
     {
        var oWnd = $find("RadWindow2");
        oWnd.show();
        return false;
     }
  function OnClick(txtid)
    {
        var textbox1 = document.getElementById(txtid);
       var textbox2 = document.getElementById(document.getElementById('HiddenField1').value);
        textbox2.value = textbox1.value;
        return false;
     }
</script>

C#:

protected void Page_Load(object sender, EventArgs e)
   {
       RadWindow window = (RadWindow)this.FindControl("RadWindow2");
       Button btn = (Button)window.ContentContainer.FindControl("Button2");
       TextBox txt2 = (TextBox)window.ContentContainer.FindControl("TextBox2");
       btn.Attributes.Add("onclick", "return OnClick('" + txt2.ClientID + "');");
   }


protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridDataInsertItem && e.Item.OwnerTableView.IsItemInserted)
       {
           GridDataInsertItem inserItem = (GridDataInsertItem)e.Item;
           TextBox txt = (TextBox)inserItem.FindControl("TextBox1");
           HiddenField1.Value = txt.ClientID;
       }
   }
