Unable to hide Label in RadGrid in Edit Mode

[Milan Gurung]

Hi,

Why is it not possible to hide the label during edit mode?

For instance, in the following code, "lblInvoiceDetailID" is not hidden even when visible property is set to false in edit mode....

<telerik:GridTemplateColumn DataField="InvoiceDetailID" HeaderText="InvoiceDetailID" UniqueName="InvoiceDetailID" Display="False">

                        <ItemTemplate>

                            <asp:Label ID="lblInvoiceDetailID" runat="server" Text='<%# Bind("InvoiceDetailID") %>'  Visible="false"> </asp:Label>

                        </ItemTemplate>

                        <EditItemTemplate>

                            <asp:TextBox ID="txtInvoiceDetailID" Text='<%# Bind("InvoiceDetailID") %>'  runat="server" ReadOnly="true" Visible="false"></asp:TextBox>

                        </EditItemTemplate>

                    </telerik:GridTemplateColumn>

Any help is highly appreciated.

Many thanks.

Hello Milan,

I think that what you actually see is the HeaderText of the column and not the label set in the ItemTemplate. To hide the HeaderText when the column is in edit mode just set EditFormHeaderTextFormat = "". Here is the modified markup:

<telerik:GridTemplateColumn EditFormHeaderTextFormat="" DataField="InvoiceDetailID"
                    HeaderText="InvoiceDetailID" UniqueName="InvoiceDetailID">
                    <ItemTemplate>
                        <asp:Label ID="lblInvoiceDetailID" runat="server" Text='<%# Bind("InvoiceDetailID") %>'> </asp:Label>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:TextBox ID="txtInvoiceDetailID" Text='<%# Bind("InvoiceDetailID") %>' runat="server"></asp:TextBox>
                    </EditItemTemplate>
                </telerik:GridTemplateColumn>

I hope this helps.

Hi,

Is there a possibility to change EditFormHeaderTextFormat value (column label in Edit/Insert) based on the value of a combo box in radgrid? OnSelectIndexChanged.

Hi Samir,

I guess you want to set the EditFormHeaderTextFormat of a template column, when the value in RadComboBox in EditItemTemplate is selected. Please try the following code snippet.

ASPX:

<telerik:GridTemplateColumn HeaderText="CustomerID" UniqueName="CustomerID">
    <ItemTemplate>
        <%#Eval("CustomerID") %>
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server" DataSourceID="SqlDataSource2" AutoPostBack="true" DataTextField="CustomerID" DataValueField="CustomerID" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
        </telerik:RadComboBox>
    </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
  RadComboBox combo = (RadComboBox)sender;
  string value = combo.SelectedItem.Text;
  RadGrid1.MasterTableView.GetColumn("CustomerID").EditFormHeaderTextFormat = value;
  RadGrid1.Rebind();
}

Thanks,
Princy

Thanks Princy,
This part works but it's not exactly my scenario. I need combo in one column to change the title and hide textbox (EditItemTemplate) in the second column (GridTemplateColumn), depend on combo selectedvalue. Another problem is that RadGrid1.Rebind(); reset SelectedValue in the combo.

Hi Samir,

Please try the following sample code snippet to change the EditFormHeaderTextFormat of a column and hide its TextBox.

ASPX:

<telerik:GridTemplateColumn HeaderText="CustomerID" UniqueName="CustomerID">
    <ItemTemplate>
        <%#Eval("CustomerID") %>
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server" DataSourceID="SqlDataSource2"
            AutoPostBack="true" DataTextField="CustomerID" DataValueField="CustomerID" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
        </telerik:RadComboBox>
    </EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn HeaderText="ShipCity" UniqueName="ShipCity">
    <ItemTemplate>
        <%#Eval("ShipCity")%>
    </ItemTemplate>
    <EditItemTemplate>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

string value = string.Empty;
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem edit = (GridEditableItem)e.Item;
        RadComboBox combo = (RadComboBox)edit.FindControl("RadComboBox1");
        if (value != string.Empty)
        {
            //Hide the TextBox and store the value in ComboBox
            TextBox txt = (TextBox)edit.FindControl("TextBox1");
            txt.Visible = false;
            combo.SelectedValue = value;
        }
        else
            combo.SelectedValue = DataBinder.Eval(edit.DataItem, "CustomerID").ToString();
    }
}
protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadComboBox combo = (RadComboBox)sender;
    GridEditableItem edit = (GridEditableItem)combo.NamingContainer;
    value = combo.SelectedItem.Text;
    RadGrid1.MasterTableView.GetColumn("ShipCity").EditFormHeaderTextFormat = value;
    RadGrid1.Rebind();
    combo.SelectedItem.Text = value;
}

Thanks,
Princy
