Enum datasource

Hi there i need help on binding enum to a radgrid.

I have enum below:

                    <div>&nbsp;<i>public enum UserType</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;{</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Default = 1, &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Parameters = 2,</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Students = 3,</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Marks = 4,</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;}</i></div>         

and my radgrid defined as follows:

                    <div><i>&lt;telerik:RadGrid id="userGrid" runat="server" AllowFilteringByColumn="false" Width="100%" &nbsp;</i></div><div><i>&nbsp;&nbsp; &nbsp; AutoGenerateColumns="false" PageSize="30" AllowPaging="true"&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp;&lt;MasterTableView&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;Columns&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;telerik:GridTemplateColumn AllowFiltering="false" Resizable="true" UniqueName="value" HeaderText="Pages"&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;ItemTemplate&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;asp:Label ID="asplabelValue" runat="server" ForeColor="Black" Text='&lt;% #Bind("enumValue") %&gt;' Font-Size="Medium"&gt;&lt;/asp:Label&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;/ItemTemplate&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/telerik:GridTemplateColumn&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;telerik:GridTemplateColumn AllowFiltering="false" Resizable="true" UniqueName="pages" HeaderText="Pages"&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;ItemTemplate&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;asp:Label ID="aspPgesLabel" runat="server" ForeColor="Black" Font-Size="Medium" Text='&lt;% #Bind("enumText") %&gt;'&gt;&lt;/asp:Label&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;/ItemTemplate&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/telerik:GridTemplateColumn&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;/Columns&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;/MasterTableView&gt;</i></div><div><i>&nbsp;&nbsp; &nbsp;&lt;/telerik:RadGrid&gt;</i></div>

Specified cast is not valid. error on RadTimePicker value bind to a grid cell

<ItemTemplate>
<telerik:RadTimePicker ClientEvents-OnDateSelected="OnDateSelected" ID="txt_InD1" runat="server" Width="86" SelectedDate='<%# Eval("InDay1") %>' ></telerik:RadTimePicker>
</ItemTemplate>

When I run the project, I get an error on the line above saying "Specific cast is not valid" . Some values coming from the db are empty strings and I am guessing thats causing this issue. How can I fix empty strings and null values. my db field is a char(5) and I am only storing the time values such as 3:31, or 4:30 or 12:58 etc.

In insert/edit mode, grid is sorting on [ENTER] key

So, I'm trying to set up my grid with keyboard shortcuts. The following shortcuts work well: grid focus (ctrl-Y), item navigation (up/down keys), insert new item (ctrl-I), edit active item (enter key), and cancel insert/edit (esc key). However, when an item is in insert/edit mode and I want to save the changes, I should be able to hit the enter key -- but, the grid sorts and I lose all my changes when I hit the enter key. Why is the grid sorting??? I imagine that if I can solve the sorting issue, then the changes will be saved appropriately -- I hope.

Below is my grid markup...

                                <telerik:RadGrid ID="grdCodeLists" runat="server"

[Solved] Custom Forms in RadGrid when you don't have an aspx page

Since I'm developing my user interface elements as WebParts (class libraries) in MOSS 2007, I don't have the luxury of an .aspx page. And without an aspx page, i have to try and convert the declarative examples found on this site to work programmatically. I'm having a difficult time trying to create a custom form in a RadGrid using my own controls instead of using the auto-generated form provided by the RadGrid itself. One way I've seen this is through the use of Templates where you provide your own form to the "MasterTableView.EditFormSettings.FormTemplate". I can't find an example where this is all handled programmatically. In this situation, is it preferred that I just use the RadGrid to display a list and redirect the user to another page where the form will reside, passing the primary key as part of the query string? Or should I write my form as a class that inherits from "System.Web.UI.ITemplate" and set my RadGrid's "FormTemplate" to this class? I like the template route but I can't seem to find any good examples.

A basic example would be a RadGrid with a few rows of data... the user clicks the "Edit" button and my custom form will display itself as a "GridEditMode.PopUp".

RadGrid - Definition for "Rows"

I receive the error "'Telerik.Web.UI.RadGrid' does not contain a definition for 'Rows' and no extension method 'Rows' accepting a first argument of type 'Telerik.Web.UI.RadGrid' could be found (are you missing a using directive or an assembly reference?)" when trying to iterate through the rows of a radgrid and get the values of a specific column.

Essentially what I am trying to do is get all values for a specific column and put those values in a comma delimited list - this is done while the rad grid is being created...any help with that would be greatly appreciated.

Here is an example I used for a regular gridview prior to switching to a radgrid...

foreach (GridViewRow gvr in gvCustomerList.Rows)

{

sIen += gvr.Cells[0].Text +

",";

}

That seemed to work but since I have switched to using the RadGrid it doesn't.

Thanks!

iFrame Content not Rendering with RadAjaxManager

Hi,

I have a page which contains a drop down list and a control from Atalasoft which is essentially an image viewer.

The Atalasoft control has its own AJAX and when it renders it'll render with iFrames in it. The control is also in an ASP.NET panel.

I've set the AJAX Manager to update the panel whenever the drop down list selection changes.

Unfortunately, the content within the Atalasoft control's iFrames is not rendered.

Any help on this would be greatly appreciated.

Thanks,
Darren
