Hello,
I have a RadGrid that needs to have a editable text box for each row open and ready by default.
What is better for a RadGrid with 100 -300 Rows, using a RadNumericTextBox or a GridNumericColumnEditor?
See below:

<telerik:GridTemplateColumn DataField="Price" HeaderText="Price" 
            SortExpression="Price" UniqueName="TemplateColumnPrice">
            <ItemTemplate>
                <telerik:RadNumericTextBox ID="txtPrice" runat="server" EmptyMessage="type ..." ShowSpinButtons="True" Type="Currency" width="200px" InvalidStyleDuration="100" Value='<%# Convert.ToDecimal(DataBinder.Eval(Container.DataItem, "Price")) %>'>
                    <NumberFormat AllowRounding="True" KeepNotRoundedValue="False" />
                </telerik:RadNumericTextBox>
                <asp:RequiredFieldValidator ID="rqPrice" ControlToValidate="txtPrice" runat="server" ErrorMessage="<%$ Resources:Backend, Required %>"/>
            </ItemTemplate>
        </telerik:GridTemplateColumn>

Or using the: GridNumericColumnEditor

<telerik:GridTemplateColumn DataField="Price" HeaderText="Price"
SortExpression="Price" UniqueName="TemplateColumnPrice">
<ItemTemplate>
<telerik:GridNumericColumnEditor ID="GridNumericColumnEditor1" runat="server">
<NumericTextBox EmptyMessage="type ..." ShowSpinButtons="True" Type="Currency" width="200px" InvalidStyleDuration="100" Value='<%#Bind("Price") %>' ID="txtPrice">
<NumberFormat AllowRounding="True" KeepNotRoundedValue="False" />
</NumericTextBox>
</telerik:GridNumericColumnEditor>
</ItemTemplate>
</telerik:GridTemplateColumn>

Hello aron,

Having a column editor will reduce the footprint of the page. However, please keep in mind that a column editor is used in a slightly different fashion, as demonstrated in the code snippet below:

.aspx
 <telerik:RadGrid AllowMultiRowEdit="true" 
         ID="RadGrid1" runat="server" DataSourceID="AccessDataSource1" GridLines="None" OnPreRender="RadGrid1_PreRender">  
            <MasterTableView AutoGenerateColumns="False" DataSourceID="AccessDataSource1">  
                <RowIndicatorColumn> 
                    <HeaderStyle Width="20px" /> 
                </RowIndicatorColumn> 
                <ExpandCollapseColumn> 
                    <HeaderStyle Width="20px" /> 
                </ExpandCollapseColumn> 
                <Columns> 
                  
                <telerik:GridEditCommandColumn> 
                </telerik:GridEditCommandColumn> 
                  
                    <telerik:GridBoundColumn DataField="ShipName" HeaderText="ShipName" SortExpression="ShipName" 
                        UniqueName="ShipName">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridBoundColumn DataField="ShipAddress" HeaderText="ShipAddress" SortExpression="ShipAddress" 
                        UniqueName="ShipAddress">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" SortExpression="ShipCity" 
                        UniqueName="ShipCity">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridBoundColumn DataField="UnitPrice" DataType="System.Decimal" HeaderText="UnitPrice" 
                        SortExpression="UnitPrice" UniqueName="UnitPrice" ColumnEditorID="GridNumericColumnEditor1">  
                    </telerik:GridBoundColumn> 
                      
                     
                      
                </Columns> 
            </MasterTableView> 
            <FilterMenu EnableTheming="True">  
                <CollapseAnimation Duration="200" Type="OutQuint" /> 
            </FilterMenu> 
        </telerik:RadGrid><asp:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="~/App_Data/Nwind.mdb" 
            SelectCommand="SELECT TOp 100 [ShipName], [ShipAddress], [ShipCity], [UnitPrice] FROM [Invoices]">  
        </asp:AccessDataSource> 
          
          
      <telerik:GridNumericColumnEditor ID="GridNumericColumnEditor1" runat="server">  
<NumericTextBox runat="server" 
  ShowSpinButtons="True" Type="Currency" width="200px" InvalidStyleDuration="100" Value='<%#Eval("Price") %>' ID="txtPrice">  
<NumberFormat AllowRounding="True" KeepNotRoundedValue="False" /> 
</NumericTextBox> 
</telerik:GridNumericColumnEditor> 

I hope this gets you started properly.

Thanks for the reply.

By default this the NumericColumnEditor appears on edit mode.

How can I get it to appear on the default mode, since my users will make the edits right from page load.

Hi aron,

In this case, you can put the control in edit mode by default.
I hope this helps.

After doing this on page load, is it still faster and less foot print than using a
ItemTemplate with a RadNumericTextBox?

Hi aron,

Since all the items will be rendered in edit mode, there would be little difference between the two scenarios.
