hi,
you can define CommandArgument and CommandName for your link button,For example :

ASP.NET

<ItemTemplate>
<asp:LinkButton ID="user" runat="server" CssClass="grid_Link" CommandArgument='<%# Eval("idHuman") %>' CommandName="Edit" Text='<%# Eval("userName") %>'></asp:LinkButton>
</ItemTemplate>

and in RowCommand event of gridview get commandArgument :

C#

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        switch (e.CommandName)
        {
            case "Edit":
                {
                    string userName = e.CommandArgument.ToString();
                }
                break;
        }
    }

Hi,
You need to use LinkButton_Command of your LinkButton. Just set the CommandName of the LinkButton to something(for instance 'Select') and Bind the CategoryId to it's CommandArgument. Then, on LinkButton_Command you can get the CategoryId of that row which it's LinkButton is clicked.

I hope it helps,
Cheers.

Solution 3

Try this in Row Command event of grid view

C#

int rowindex = Convert.ToInt32(e.CommandArgument);
int MRLID = Convert.ToInt32(gvMRLSearch.DataKeys[rowindex].Value); //gvMRLSearch is gridview name
