row.Cells[4].Text returns nothing in GridView1_SelectedIndexChanged?

Question

I have a GridView in my page :

Answer 1

There is no Text as your data is stored in controls. You need to search for the control you want and pull the Text out of.

Eg:

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    GridViewRow row = GridView1.SelectedRow; 
    string temp = row.Cells[4].FindControl('LabelGridViewBankName').Text; 
    LabelResult.Text = temp; 
}

Optionally you could could key off the DataKey property if you are using it and then use it to search your datasource for the value you want.

Answer 2

//this will give you control over the textbox object
var field = (TextBox)(GridView1.Rows[e.RowIndex].FindControl("your_control_ID"));
//and here you can access the text
string temp = field.Text;

Answer 3

If it's a TemplateField, you have to use the FindControl("control ID") option, not the text fo the cell. I count cell 4 as being a templatefield...
