Data Grid

[asraj16]

Hi,
I want to disable a field in a Data Grid. When I click an edit button in a Data Grid, I need to disable a field in that corresponding row. How to do that?

Can't you just make the field Read Only?

Hope everyone is having a great day!

Thanks - Jennifer

I can do that. But when I click update button I need to enable this fields and disable other fields.

Click on Edit : disable some fields

Click on Update : enable those disabled fields, and disable other fields.

In the same events, Calling the same page.

How to do that?

I am not sure but I would investigate the ItemDataBound event. The following is one that I use to change a LinkButton based on the selected row. Hopefully this will point you in the right direction.

public void dg_ItemDataBound(Object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) {
if (e.Item.ItemType != ListItemType.Header & e.Item.ItemType != ListItemType.Footer) {
LinkButton lnkBtn = (LinkButton)e.Item.Cells[0].Controls[1];

string strItem = Convert.ToString(dg.DataKeys[e.Item.ItemIndex]);

lnkBtn.Font.Size = FontUnit.Parse(Convert.ToString((intUnit + Convert.ToInt32(lnkBtn.Font.Size.Unit.Value-10))+"px"));

if (strItem == Convert.ToString(sb.getCurrentValue("Selected_IN",strUser))) {
lnkBtn.ForeColor = colorTextBack;
lnkBtn.BackColor = colorMain;
}
else {
lnkBtn.ForeColor = colorMain;
}
}
}

Hope everyone is having a great day!

First step to disable DG record...
this would be the onEditCommand event...

    Sub DataGrid_Edit(Sender As Object, E As DataGridCommandEventArgs)
        If Not isEditing Then
            DataGrid1.EditItemIndex = e.Item.ItemIndex
            BindGrid()
            [b]DataGrid1.Items(DataGrid1.EditItemIndex).Cells(3).enabled = false[/b]
        End If
    End Sub

i noticed that you cannot perform the update when disabled though... so...i will see what i can do on reenabling on the update command.
