how to get click event from a button in gridview

Question

Hi,

I am working on a app where i need to get the click event of a button in gridview. I am not getting it in row command may be because i am adding it dynamically as follows:

protected void gviewTemplate_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.Cells[1].Text != e.Row.Cells[2].Text)
        {
            e.Row.BackColor = System.Drawing.Color.Red;
            LinkButton lbtnReload = new LinkButton();
            lbtnReload.CommandArgument = e.Row.Cells[12].Text;
            lbtnReload.Attributes.Add("onclick", "javascript:ShowDiv()");
            lbtnReload.CommandName = "reload";
            lbtnReload.Text = "Reload";
            e.Row.Cells[1].Controls.Add(lbtnReload);

            DataTable dt = (DataTable)ViewState["update"];
            DataRow dr = dt.NewRow();
            dr["id"] = e.Row.Cells[0].ToString();
            dr["image"] = e.Row.Cells[1].ToString();
            dt.Rows.Add(dr);
        }
    }
}

protected void gviewTemplate_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "reload") 
    { 
        hdnfield.value = int.Parse(e.CommandArgument.ToString()); 
    } 

    btnFuImage.Visible = true; fuploadImage.Visible = true; 
} 

I have displlayed it in gridview in following manner

<asp:BoundField ItemStyle-Width="100" DataField="Uploded" HeaderText="Uploaded Image" >  

I need to get values from first column of this grid and update it into some hidden variable so that i can use it later. How will i do it. Thanks in advance

Answer 1

Hello,

For a button, use a ButtonField and specify a commandname, which will fire the rowcommand event. BoundField doesn't render a button. If you want to click a boundfield, that's a more specialized setup...

Which are you trying to use as the click?

If you are just trying to grab one value and store it in a HiddenField for later why dont you just put that value in a javascript function and put it in the HiddenField from there

lbtnReload.Attributes.Add("onclick", "javascript:ShowDiv(); SaveValue('" + value + "'); return false;);

This will prevent you from having to go to the server which will be much faster

Also why dont you just use a TemplateField and make a button in there it will be easier to control everything yourself through that
