I'm having trouble getting / find (specific) information out of a gridview.
I am using VB.net and an MS Access database.
I want Label2 to show 'klantnr exists' IF gridview1 has value 0 Else don't show anything.
( my gues is somthing like: If me.gridview1.rows.findcontrol("klantnr") = 0 Then me.label2.Text = "klantnr exists" but offcourse this doesnt work )
How can i find data inside gridview? using VB.net
Thanx in advanced

Please be little bit more accurate. You can the find the value of a cell in a gridview like
e.Row.Cells(0).Text; This can be done in a RowDataBound event of the GridView.
If you want to find a control then:
For example textbox then
then to read the value from the textbox u do txt.Text;
Other wise after the GridView has been built you can loop through the GridView Rows
foreach(GridViewRow gvRow in GridView1.Rows)
//Get the values of cells or find controls here.

The actual thing i'm trying to do:
I have a gridview which contains a column called 'klantnr' within this gridview I can edit and delete rows. But if there is a row where 'klantnr' is 0 then some command must tell not to delete this row. (course this row is always needed)
OR even beter.
If there is a row with klantnr is 0 then do not show this row in the gridview.
I don't have any code in VB.net only a template in asp.net with no commands yet.
This would make sense but I don't know in what command (rowdeleting?)
Label).Text.ToString() = "0")

Hi dannx1986 ,
Yes , rowdeleting event is one good place to put your code in.
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
GridViewRow row = this.GridView1.Rows[e.RowIndex];
Label lbl = row.FindControl("klantnr") as Label;
if (lbl.Text == "0")
e.Cancel = true;
