Get Gridview Row Index

Question

I am using the below code to get the row index

protected void gvESAPending_RowCommand(object sender, GridViewCommandEventArgs e)

    {
        try
        {
            lblMsg.Text = "";
            int index = Convert.ToInt32(e.CommandArgument);
            GridViewRow row = gvESAPending.Rows[index]; // Here incorrect format error is coming
        }
     }

But the index value is coming as 0. What is wrong here?

Aspx Code

'> '>

Solution

You can add OnRowCreteEvent

ASPX:

<asp:gridview id="gvESAPending" onrowcreated="gvESAPending_RowCreated" ...

CS :

protected void gvESAPending_RowCreated(Object sender, GridViewRowEventArgs e)
  {
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      LinkButton addButton = (LinkButton)e.Row.Cells[0].Controls[0];

      addButton.CommandArgument = e.Row.RowIndex.ToString();
    }

  }

I got this error {System.InvalidCastException: Unable to cast object of type 'System.Web.UI.WebControls.GridView' to type 'System.Web.UI.WebControls.Button'.

What is the error ? Can you give us the aspx code or follow the recommendation of @huMpty duMpty

[Shantanu Sen]

int index = Convert.ToInt32( e.CommandArgument); This is returning 0 so it should work. But its giving error

[Shantanu Sen]

<asp:ButtonField ButtonType="Button" CommandName="App" Text="Approve"> <ControlStyle BackColor="White" BorderStyle="None" Font-Underline="True" ForeColor="Blue" /> </asp:ButtonField> <asp:ButtonField ButtonType="Button" CommandName="Dec" Text="Decline"> <ControlStyle BackColor="White" BorderStyle="None" Font-Underline="True" ForeColor="Blue" /> </asp:ButtonField>

Ok that why the index value is coming as 0. Can you explain what you wanna do ??

[Shantanu Sen]

Already the gridview is bound with data .. I am clicking a buttonfield and thus need to get the row number

[GeorgesD]

gridview is bound with data so rows are created !

[Shantanu Sen]

all the examples are showing can be achieved by gvESAPending_RowCommand, why my code is not working .. am i missing something4

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

try this Int32.Parse(e.CommandArgument.ToString()) something may be screwy with the convert function, this should boil it down and give you something more useful to work with. If you really want to get fancy set string var = e.CommandArgument.ToString() put a break point right after it and check it out in the locals window to make sure your getting a value
