Hi,
I have Footer row in my Radgrid with Text box as footer item template control for few columns. User can enter a value in text box and then click button to save it in database. I am not getting textbox value at runtime in button click event, its always ""

I am using the below code to read access footer value.
GridFooterItem footerItem = (GridFooterItem)gridBulkEdit.MasterTableView.GetItems(GridItemType.Footer)[0];                       
RadTextBox texte = (RadTextBox)footerItem.FindControl("txtPortfolioID");

please advise.

Hi Giriprasad,

Your code looks correct, please make sure you haven't set its visibility to false. Here is a sample code that i tried which works fine. Please provide your full code if this doesn't help.

ASPX:
<telerik:GridTemplateColumn UniqueName="GridTemplateColumn">
    <ItemTemplate>
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    </ItemTemplate>
    <FooterTemplate>
        <telerik:RadTextBox ID="RadTextBox1" runat="server">
        </telerik:RadTextBox>
    </FooterTemplate>
</telerik:GridTemplateColumn>

C#:
protected void Button1_Click(object sender, EventArgs e)
{
    GridFooterItem footeritem = (GridFooterItem)RadGrid1.MasterTableView.GetItems(GridItemType.Footer)[0];
    RadTextBox txt = (RadTextBox)footeritem.FindControl("RadTextBox1"); //Access the RadTextBox
    string footertext = txt.Text;//Get the Footer Text;
}

Thanks,
Princy

Hi Princy,
Thanks for your reply.

I have not set the visibility to false and I'm able to access the textbox object but the value is always empty. See my design code below. 

<telerik:GridTemplateColumn UniqueName="PortfolioID" DataField="DLS_PORTF" HeaderText="Portfolio ID" >
                        <ItemTemplate>
                            <%#Eval("DLS_PORTF") %>
                          </ItemTemplate>
                        <FooterTemplate>
                          <telerik:RadTextBox ID="txtPortfolioID" runat="server" Wrap="true" >
                            <ClientEvents  />
                          </telerik:RadTextBox>
                        </FooterTemplate>
                      </telerik:GridTemplateColumn>

Hi Giriprasad,

I was not able to replicate the issue, here is a sample code snippet , please try and see hows it different from your code.

ASPX:
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" AllowPaging="true"
    ShowFooter="true" OnNeedDataSource="RadGrid1_NeedDataSource">
    <MasterTableView>
        <Columns>
            <telerik:GridBoundColumn DataField="ID" HeaderText="ID" UniqueName="ID" />
            <telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name" />
            <telerik:GridTemplateColumn UniqueName="Number" DataField="Number" HeaderText="Number">
                <ItemTemplate>
                    <%#Eval("Number")%>
                </ItemTemplate>
                <FooterTemplate>
                    <telerik:RadTextBox ID="txtNumber" runat="server" Wrap="true">
                    </telerik:RadTextBox>
                </FooterTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" Text="Save" OnClick="Button1_Click" />

C#:
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    dynamic data = new[] {
 new { ID = 1, Name = "Name1", Number=123},
 new { ID = 2, Name = "Name2", Number=234},
 new { ID = 3, Name = "Name3", Number=234},
 new { ID = 4, Name = "Name4", Number=456},
 new { ID = 5, Name = "Name5", Number=567},
 new { ID = 6, Name = "Name6", Number=567},
 new { ID = 7, Name = "Name7", Number=789},
 new { ID = 8, Name = "Name8", Number=896},
 new { ID = 9, Name = "Name9", Number=741}
};
    RadGrid1.DataSource = data;
}
protected void Button1_Click(object sender, EventArgs e)
{
    GridFooterItem footeritem = (GridFooterItem)RadGrid1.MasterTableView.GetItems(GridItemType.Footer)[0];
    RadTextBox txt = (RadTextBox)footeritem.FindControl("txtNumber");
    string footertext = txt.Text;   
}

Hi Princy,
I have tried your code, but if I type any text and check the text box text value in button click, I get "". Did you manage to get the text box value at run time with your code?

Giri

Hi Kommuri,

When using .FindControl(), you must pass to it the same string that is passed to the ID property of the control when creating it. Perhaps you should consider generating the ID of the textbox by using the UniqueName of its column, so it is predictable and you can generate it again when accessing the textbox.

It is also important to note that you should create controls either in the markup, or with every postback (meaning, in Page_Init, or in the ItemCreated event).

Hi,

I have two radgrids 1 and 2. Ragdrid1 has footer sum aggregate of column 'SID' and Radgrid2 has footer sum aggregate of 'LOADS'. I want to compare both footer values. Please suggest.

Thank you.

I got it.

If TypeOf e.Item Is GridFooterItem Then
            Dim footer1 As GridFooterItem = CType(RadGrid1.MasterTableView.GetItems(GridItemType.Footer)(0), GridFooterItem)
            Dim gstrSidTotal As String = footer1("QTY_EXP").Text

            Dim footer2 As GridFooterItem = CType(RadGrid2.MasterTableView.GetItems(GridItemType.Footer)(0), GridFooterItem)
            Dim gstrLoadTotal As String = footer2("TOTAL_QTY").Text

end If

But now, is there a way to get only values. Here, the values i get are like 'SUM: 1200' or 'SUM: 800' or so on. Is there a way I could access only the values after ':'?

Hello Kiranmayee,

You can parse out the text from the cell contents. Since you know what the original aggregate is, you know the format that is set for the footer so you can string.Replace() it.

Alternatively, implement your own custom aggregation and you will be able to store actual results in an object in the page class. Here's how to implement your own aggregate functions: https://www.telerik.com/support/kb/aspnet-ajax/grid/details/how-to-create-custom-aggregate-functions.
