how to manipulate a CommandItemTemplate button on its own click

[Nabeel]

The scenario:

I have a MasterTableView and it contains one DetailsTable. And the GridTableView contains a button in its CommandItemTemplate section. I want to manipulate that button programatically on its own click. For example, change its caption or visibility when it is clicked by certain user etc.

The markup for the CommandItemTemplate is below:

<CommandItemTemplate>
                                <div style="padding: 5px 5px; text-align:right" >
                                    <asp:Button ID="btnSaveAction" runat="server" SkinID="Save" 
                                        CausesValidation="false" Text='​Save'  CommandName="​Save" CommandArgument='<%# Eval("ID") %>' />
                                </div>
                            </CommandItemTemplate>​

Hello Nabeel,

You can use its own OnClick or OnCommand event handlers to achieve this requirement:

<asp:Button ... OnClick="btnSaveAction_Click" />

C#:

protected void btnSaveAction_Click(object sender, EventArgs e)
{
    Button button = (Button)sender;
    button.Text = "Success";
}

Hope this helps. Please give it a try and let me know if it works for you.

But the button needs to take actions against a particular ID (or any field within DataKeys of that particular row)

[Nabeel]

I mean such buttons do not have CommandArgument property available to them then how can I get the ID of that particular row which is clicked. For example tha MasterTable is ​INBOX and GridTableView in details table is LegalMails which contains some rows (emails). Now there is some CommandItemTemplate (button) for GridTableView so ultimately every ​row in the INBOX table will contain a command button. If a user clicks on that command button, i want to fetch the row ID of INBOX (not LegalMails row ID)

Hi Nabeel,

You can achieve this requirement using the following approach:

protected void btnSaveAction_Click(object sender, EventArgs e)
{
    Button button = (Button)sender;
    GridDataItem item = (GridDataItem)button.NamingContainer;

    // I assume this event handler would be raised
    // for the detail table button
    string value = item.GetDataKeyValue("LegalMails").ToString();
    button.Text = value;
}

Looking forward to hearing from you.
