How can I get a value of the DataKeyName of a GridView Row when I have a button inside a row that have an OnClick event. In my OnClick event of my button I want to get a the DataKeyName of the row where the button resides.
Is this possible?
<asp:GridView ID="myGridView" run="server">
<Columns>
<asp:TemplateField HeaderText="Column 1">
<ItemTemplate>
... bunch of html codes
<asp:Button ID="myButton" UseSubmitBehavior="false" runat="server" Text="Click Me" onclick="btnClick_Click" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
In my codebehind
protected void btnClick_Click(object sender, EventArgs e)
{
// How can I get the DataKeyName value of the Row that the Button was clicked?
}
When I'm working with a GridView, I usually do not use the
OnClick
event for buttons. Instead, I use theOnRowCommand
event on the GridView, and bind data to theCommandArgument
property of the button. You can retrieve the command argument from theGridViewCommandEventArgs
parameter of the event handler.You can use the
CommandName
parameter to bind an arbitrary string to distinguish between any different kinds of buttons you have. Note that some command names are already used for other events, such as "Edit", "Update", "Cancel", "Select" and "Delete".Update:
Here is an example, assuming the data key is called "ID":
And in the code-behind:
