Hi all,

protected void update_Status_Click(object sender, EventArgs e)
    {
        
        List<int> id = new List<int>();
       
        foreach (GridViewRow row in GridView1.Rows) 
        {
            int i = row.RowIndex;
        
            CheckBox cb = (CheckBox)row.FindControl("SelectCashout");
 
            if (cb != null && cb.Checked) 
            {
                

                if (GridView1.Rows[i].Cells[2].Text == "Requested")
                {
                    int x = Convert.ToInt32(GridView1.Rows[i].Cells[0].Text);
                    id.Add(x);
                }
            } 
        } 
    }

When I debug it I am getting "GridView1.Rows[i].Cells[2].Text" value as empty string.
This is not a Gridview event, it is button event out side the gridview.
I tried row.Cells[2].Text it doesn't help...

What am I missing here? any help thanks

Hi Andy,
Thanks for your reply. It's not Edit/Update button on Gridview.
I am giving option to the user to select which rows he wants to update.
Based on his selection through checkbox I have to update just one cell value in the gridview and collect primary key of that row in the table so I will update datasource at backend(That code I havn't included)

Hope you understood. updating one cell value is not mandatory because I am updating datasource and I can rebind it. Collecting that row's Primary key(Datasource Table's) is

"GridView1.Rows[i].Cells[0].Text" important to update database.

Thanks

Hi Jayadheer,

I think you use CommandField in GridView and click on this CommandField to edit GridRow, right???

If you did that, please re-bind datasource for the GridView, because when the template control in the column turns to edit mode, the default text is empty. So you must re-bind the GridView

Hope it helps you.

Andy

Solution 3

In my code, GridView1.Rows[i].Cells[2].Text is OK, has value. Please see the column 2nd on the Grid, does it have value?

Solution 7

Hi,

LOOK ON YOUR GRIDVIEW, it has VALUE or NOT? If it does not have VALUE, maybe you didn't bind data for this field or you missed DataField property.

I can't get the closing int32 tag to go away, it should not be there in the actual code. I keep trying to remove it, but it shows up when I try to update. Please don't down-rate the answer based on this error with CP's posting logic.

Thanks for your relay.
Gridview1.Rows[i] does not have Field property... Error..
I have all columns with template fields

Oh, sorry, I forgot I was using a 3rd party gridview. I'll get back to you.

Just so I understand the question correctly. The Value of the cell is empty, is this expected? Do you want to set your int value to 0 if it is empty?
