Editable GridView
-
Hi, I have a gridview with Edit And Delete buttons. Here is one of the columns:
<asp:TemplateField HeaderText="החל מ-">
<EditItemTemplate>
<asp:TextBox ID="txtStart" Width="150px" ReadOnly="true" BackColor="LightSteelBlue" runat="server" Text='<%# Bind("startHour") %>'></asp:TextBox></EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtStartNew" Width="150px" runat="server"></asp:TextBox></FooterTemplate>
<ItemTemplate>
<asp:Label ID="lblMStart" Width="150px" runat="server" Text='<%# Bind("startHour") %>'></asp:Label></ItemTemplate>
</asp:TemplateField>I've set the TextBox in the EditItemTemplate to ReadOnly. My Problem is- that i want to change the property (ReadOnly) to False after i pressed on the Edit button if some cell has a value. I've tried to do this in the RowEditing event -
TextBox txtStart = (TextBox)GridViewIpTab.Rows[e.RowIndex].FindControl("txtStart");but i got "Object reference not set to an instance of an object". Can some one please help me with this problem? -

if (e.Row.RowType == DataControlRowType.DataRow)
{
if (GridViewIpTab.EditIndex == e.Row.RowIndex)
{
TextBox txtStart = (TextBox)GridViewIpTab.Rows[e.Row.RowIndex].FindControl("txtStart");
// Do what you need to do
}
}In RowEditing do:
GridViewIpTab.EditIndex = e.NewEditIndex; BindYourGrid();
