So, I have a scenario that I'm not sure how to handle.  We have some pages that have a huge amount of numeric textboxes on them and having them each as a  RadNumericTextBox just doesn't work very well.   So I looked to RadInputManager.   Problem is it seems that me that there is an issue when dealing with a container of controls, take a GridView for example.   I may have 20 rows each with 5 numeric boxes in them.   1 box may require 0 decimal places for integer, 2 boxes may require 2 decimal places for money and 2 boxes may require 3 decimal places for %.   Ideally I could create a RadInputManager outside of that repeater and specify different decimals for each box, but I'm pretty sure that can't be done, because the only input to the RadInputManager is a single ClientID, not an ability to specify the container and then the name inside that container.  Is that correct? 

So, my next thought is to try to create 3 RadInputManagers inside of the GridView .   That's 3 managers total.  But I don't think there's a way to do that either, at least in the .aspx page. 

So my next thought which I'm pretty sure would work, is inside of each Template Column (or where relevant), or maybe just the first column, create three managers that each define number of decimal places and then set the ids there.   While I imagine this would probably work, my question is would there be a big hit on performance creating 3 managers per row?  Could it be done better in a code behind?  Is there a better solution I haven't thought of?


An Example of this last idea with just 2 managers:

<GridView .....>

<asp:TemplateField>

<ItemTemplate>

<telerik:RadInputManager ID="RadInputManager2" runat="server">

<telerik:NumericTextBoxSetting DecimalDigits="2">

<TargetControls>

<telerik:TargetInput ControlID="SortOrder" />

</TargetControls>

</telerik:NumericTextBoxSetting>

</telerik:RadInputManager>

<asp:TextBox runat="server" ID="SortOrder" Text='<%#Eval("SortOrder") %>'></asp:TextBox>

</ItemTemplate>

</asp:TemplateField>

<asp:TemplateField
<ItemTemplate>
<telerik:RadInputManager ID="RadInputManager1" runat="server">
<telerik:NumericTextBoxSetting DecimalDigits="0">
<TargetControls>
<telerik:TargetInput ControlID="ItemAmount" />
<telerik:TargetInput ControlID="ItemAmountAdj" />
</TargetControls>
</telerik:NumericTextBoxSetting>
</telerik:RadInputManager>
<asp:TextBox runat="server" ID="ItemAmount" Text='<%#Eval("ItemAmount") %>'></asp:TextBox>
<asp:TextBox runat="server" ID="ItemAmountAdj" Text='<%#Eval("ItemAmountAdj") %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>

</GridView>

I have problems to erase a register from a RADGRID, associated to a SessionDataSource, which I use temporarily, playing the role of a “recipient“ ( just insert and delete).

The code the .aspx for the SessionDataSource is as below:

The code the .aspx for RadGrid is as below:

The insert I do it with the code behind and it works without any problem:
