Radgrid Detail Table Footer Items

[majith basha]

Hi Princy,

As the below code provided by you to vinayak for traversing the detail table data items(GridDataItem).
 
1. I want access the (GridFooterItem) in the detail table in item data bound event. 
 

  protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs  e)  
  {  

  if (e.Item is GridDataItem  && e.Item.OwnerTableView.Name == "Detail")   
   {  

      GridDataItem item1 = (GridDataItem)e.Item;  

      DropDownList combo = (DropDownList)item1.FindControl("DropDownList1");  

      combo.Attributes.Add("onChange", "return Change('" + item1.ItemIndex +  "');"); 
      }   

   }  

 

The reference link from  the code fetched is as follows :

Hello Majith,


Check for GridFooterItem instead of GridDataItem as shown below.


Code:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridFooterItem && e.Item.OwnerTableView.Name == "Detail")
    {
        GridFooterItem footerItem = (GridFooterItem)e.Item;
        DropDownList combo = (DropDownList)footerItem.FindControl("DropDownListFooter");
        combo.Enabled = false;
    }
}

aspx:

<Columns>
    <telerik:GridTemplateColumn UniqueName="DropDown">
        <ItemTemplate>
            <asp:DropDownList ID="DropDownList1" runat="server">
            </asp:DropDownList>
        </ItemTemplate>
        <FooterTemplate>
            <asp:DropDownList ID="DropDownListFooter" runat="server">
            </asp:DropDownList>
        </FooterTemplate>
    </telerik:GridTemplateColumn>

Hope this helps,
Princy.

Hi Princy,

The above code is clear. My Question is Can we get (GridFooterItem and GridDataItem) in the single loop.

1. The problem is I am doing the calculation in client side. I need to get Footer Item(Client ID) of the corresponding Grid data item  which is being Updated.

 I am trying the below code but unable to perform this.

if (e.Item is GridFooterItem && e.Item.OwnerTableView.Name == "Detail")

    {

               GridFooterItem footer = (GridFooterItem)e.Item;

               (footer["Template1"].FindControl("TextBox2") as TextBox).Text = sum.ToString();

               clientID = (footer["Template1"].FindControl("TextBox2") as TextBox).ClientID;



               foreach (GridDataItem gdi in RadGrid1.Items)

               {

                   if (gdi.ChildItem != null)

                   {

                       for (int i = 0; i < gdi.ChildItem.NestedTableViews[0].Items.Count; i++)

                       {

                           GridDataItem dataItem = gdi.ChildItem.NestedTableViews[0].Items[i];

                           TextBox qTextBox = dataItem.FindControl("TextBox1") as TextBox;

                           TextBox uTextBox = dataItem.FindControl("TextBox3") as TextBox;

                           Label lblCM = dataItem.FindControl("lblCM") as Label;

                           Label lblTotal = dataItem.FindControl("lblTotal") as Label;

                           if (qTextBox != null && uTextBox != null && lblCMI != null && lblTotalCMI != null)

                           {

                               (dataItem["Template1"].FindControl("TextBox1") as TextBox).Attributes.Add("onblur", "update('" + lblCM.ClientID + "'" + "," + "'" + lblTotal.ClientID + "'" + "," + "'" + uTextBox.ClientID + "'" + "," + "'" + clientID + "'" + "," + "'" + (dataItem["Template1"].FindControl("TextBox1") as TextBox).ClientID + "')");

                               (dataItem["Template1"].FindControl("TextBox1") as TextBox).Attributes.Add("onfocus", "getInitialValue('" + (dataItem["Template1"].FindControl("TextBox1") as TextBox).ClientID + "')");

                           }

                       }

                   }

               }

           }

Thanks in advance.

I have a similar scenario. My grid is rendered in edit mode.
I have a read only textbox in footer which displays the total of each rows. I am doing a client side validation that the total does not exceed 100. For that I need to hook up the client id of the textbox in the footer in my griddataitem loop.

How can i do this?

Hi MBEN,

Please try the below JavaScript code snippet to access the TextBox in the GridFooterItem.

JavaScript:

var footerTextBox = '<%=(GridFooterItem)RadGrid1.MasterTableView.GetItems(GridItemType.Footer)[0]).FindControl("RadTextBox1").ClientID %>';
var TextBox = document.getElementById(footerTextBox);

Thanks,
Princy.
