Question

I have this gridview:

<div class="content">
    <asp:GridView ID="DocumentGrid" runat="server" AutoGenerateColumns="False" OnRowCommand="DocumentGrid_RowCommand" >
        <Columns>
            <asp:BoundField HeaderText="ID" DataField="ID" ItemStyle-Width="120px"/>
            <asp:ButtonField HeaderText="Download Link" Text="Download"/>
        </Columns>
    </asp:GridView>
</div>

As you can see, DocumentGrid_RowCommand is called when the “Download” button is pressed, How can I find out what the values are of the row that was clicked?

Answer 1

If more than one button fields are there in GridView, set CommandName attribute. That way we can determine which button is pressed in RowCommand event. So always set commandName attribute.

<Columns>
 <asp:BoundField HeaderText="ID" DataField="ID" ItemStyle-Width="120px"/>
 <asp:ButtonField HeaderText="Download Link" Text="Download" CommandName="cmd"/>
</Columns>

In RowCommand event handler, GridViewCommandEventArgs.CommandArgument property returns index of row on which button is pressed.

 protected void DocumentGrid_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "cmd")
        {
            int index = int.Parse(e.CommandArgument.ToString());
            GridViewRow row = DocumentGrid.Rows[index];
            if (row.RowType == DataControlRowType.DataRow)
            {
                Response.Write(row.Cells[0].Text);
            }
        }
    }
