Accessing GridView Cells Value

I am trying to access the integer value of the first cell but I'm getting this error:

Unable to cast object of type 'System.Web.UI.WebControls.DataControlFieldCell' to type开发者_开发知识库 'System.IConvertible'.

And the value i have stored in that cell is an ID like 810

My Code

int myID = Convert.ToInt32(GridView1.Rows[rowIndex].Cells[0]);

Cells[0] returns a DataControlFieldCell object, not the cell's value.
Use the cell's Text property.

GridView1.Rows[rowIndex].Cells[0].Text

--or--

GridView1.Rows[rowIndex].Cells[0].Value

Makes programmer's life harder with these stupid ambiguities introduced by Microsoft over time.

Try this both of this codes are valued

 int SB = Convert.ToInt32(gdTest.SelectedRow.Cells[1].Text);

              ---------OR-------

int AS = Convert.ToInt32(gdTest.Rows[1].Cells[1].Text);

The recommended approach to retrieve the value of a cell in GridView/FormView is to use ExtractValuesFromCell() method. See an example below:

foreach(var row in GridView.Rows) 
{
    // retrieve all cell values in a row as a ordered dictionary.
    IOrderedDictionary cellValues = new OrderedDictionary();
    foreach(DataControlFieldCell cell in row.Cells)
    {      
            cell.ContainingField.ExtractValuesFromCell(cellValues, cell, row.RowState, true);
    }

    // now do something with the cellValues for e.g read the columns value
    // like - cellValues["EmployeeName"]
}

The returned values are strings and can be converted with the help of System.Convert class.
