How to pass multiple arguments in CommandArgument in GridView?

Question

I was working on asp.net GridView control. Now I need to edit some row data. For that I was using this code:

 <asp:LinkButton ID="btnEdit" Text="Edit" runat="server" CommandName="QuickEdit"  OnClick="btnEdit_Click"
  CommandArgument ='<%# ((CheckBox)(((GridViewRow) Container).Cells[4].Controls[0])).Checked %>'/>

And the btnEdit_Click method is:

protected void btnEdit_Click(object sender,EventArgs  e)
{
    LinkButton btn = (LinkButton)sender;
    switch (btn.CommandName)
    {
        case "QuickEdit":

        EditPanel.Visible = true;
        GridPanel.Visible = false;
        CheckBox cbRequiresState = (CheckBox)EditPanel.FindControl("checkRequiresState");

        if (btn.CommandArgument =="True")
        {
            cbRequiresState.Checked = true;
        }
        else
        {
            cbRequiresState.Checked = false;
        }

        break;
    }
}

Now, I need to pass more than one argument as CommandArgument to that btnEdit_Click method. For that what I need to do? And please suggest me a good way to utilize those arguments in that method.

Why not use the GridView OnRowCommand event?

here is an example :

in your aspx code :

<asp:ImageButton ID="btnSelect" runat="server" ImageUrl="~/Images/btnSelect.png" CommandName="Select" CommandArgument='<%# Container.DataItemIndex +";"+Eval("ID") %>' ToolTip="select" CausesValidation="False" /></ItemTemplate>

and in your code behind :

    string info = e.CommandArgument.ToString();
    string[] arg = new string[2];
    char[] splitter = { ';' };
    arg = info.Split(splitter);

I was trying like this: CommandArgument ='<%#Container.DataItemIndex+";"+((Label)(((GridViewRow)Container).Cells[1].Controls[0])).Text+";"+ ((CheckBox)(((GridViewRow) Container).Cells[4].Controls[0])).Checked %>'/> but some error was there: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

You can use a string and separate the values by ; or another character.

you can't do that ((Label)(((GridViewRow)Container).Cells[1].Cont‌rols[0])).Text. I think you need to set the command argument in the RowDataBound Event

Because CommandArgument is a simple string, concatenate the arguments you want to pass to the event putting some kind of separator among them.

Then in btnEdit_Click split the values by separator.

NOTE: Chose the sepatator so that it isn't a character contained in anyone of the parameters passed to the event.

@TamalKantiDey how many columns do you have in your GridViewRow? It seems you are trying to access an out-of-range cell...
