Hello all

i am trying to get ID value from my GridView using CommandArgument, but when it is return the row index value instead of ID value

C#

<asp:TemplateField HeaderText="           " HeaderStyle-HorizontalAlign="Center">
       <ItemTemplate>
                     <asp:ImageButton ID="imgbtnDelete" CommandName="Delete1"                          CommandArgument='<%# Eval("VisID") %>' runat="server" ImageUrl="images/button_delete.png"/>
       </ItemTemplate>
       <HeaderStyle HorizontalAlign="Center" />
</asp:TemplateField>

and this is my C# code:

C#

protected void grdAppuser_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ImageButton delBtn = (ImageButton)e.Row.FindControl("imgbtnDelete");

            delBtn.Attributes.Add("OnClick", "return confirm('Are you sure you want to delete');");

            e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.grdAppuser, "Select$" + e.Row.RowIndex);
        }


protected void grdAppuser_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");

        try
        {
            switch (e.CommandName)
            {
                case ("Delete1"):
                    
                    string id = Convert.ToString(e.CommandArgument); // the problem here this line return row index instead of ID
     }

so as i said the e.CommandArgument return row index instead of ID value.

What do you want to do with this line of code ?

e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.grdAppuser, "Select$" + e.Row.RowIndex);

CommandArgument is set for 'VisID' and will return so. What do you see in Debug ?

First of all, remove following lines from your code

C#

e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.grdAppuser, "Select$" + e.Row.RowIndex);

System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");

Then Add following events to your gridView aspx

ASP.NET

<asp:gridview id="grdAppuser" runat="server" autogeneratecolumns="false" xmlns:asp="#unknown">
OnRowCommand="grdAppuser_RowCommand" OnRowDataBound="grdAppuser_RowDataBound" Width="90%">


<asp:imagebutton id="imgbtnDelete" commandname="Delete1" commandargument="<%#Eval("VisID")%>" runat="server" imageurl="images/button_delete.png" />
</asp:gridview>

Then add this in your Row Command event, you will surely get e.CommandArgument value

C#

protected void grdAppuser_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        switch (e.CommandName)
            {
                case ("Delete1"):                    
                    string id = Convert.ToString(e.CommandArgument); 
            }
     }

Hope this will work for you.

Solution 1

If you just need to fire ImageButton event then register ImageButton event you can get value there.
