Using SelectedIndexChanged to update second grid

I am working with the web mail demo and removing the LINQ references and trying to work within the confines of the code behind.

I have the treeview on the left updating the grid in the top right (radgrid1) properly. When I click on a gridrow in the top right (radgrid1), I want to display detail text in the bottom right pane (radgrid2). I don't care what control displays it, It will just be text.

I thought selectedindexchanged on radgrid1 would get me there but it appears to be a page lifecycle issue perhaps? I have confirmed this event is firing.

    
                Protected Sub RadGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged 
        
                    RadGrid2.Rebind() 
        
                End Sub

Any ideas?

Filter problem - InvalidCastException

Hi.

I made MDX query with AdomdClient. I put result into DataSet and DataSet binded to Grid: RadGrid1.DataSource = dataset.Tables[0];

Grid loads data fine, paging works fine too, but Ive problem with filtering:

a] EnableLinqExpression = true

* filtering string works perfect

* filtering number gets InvalidCastException -> The specified cast is not valid. (translated by google) - error message in the end of post

* didnt try another datatypes (like date etc)

b] EnableLinqExpression = false

* when I press filter button, page is reloaded, but there is no filter applied.

Im totally lost, have no idea what to try next. Id be grateful for every idea.

Thank you!

error message while using EnableLinqExpression = true

Hi,

I am using RadUpload control inside a table which use the style="position:absolute" and this is blocking the RadUpload select button to open the file select dialogue window. I dont know what could be the fix for this and i have to apply the style on the panel.
I also tried with Position:relative still not working.

Code:

<tr>

Upload General Information Documents

</td>

</tr>

<tr>

<td>

<telerik:RadProgressManager ID="RadProgressManager1" runat="server" />

<telerik:RadUpload ID="RadUpload1" runat="server" InputSize="70" MaxFileInputsCount="5"

TargetFolder="~/UploadFiles">

</telerik:RadUpload>

<br />

<telerik:RadProgressArea ID="RadProgressArea1" runat="server" DisplayCancelButton="True"

ProgressIndicators="TotalProgressBar, TotalProgress, RequestSize, FilesCount, FilesCountPercent, SelectedFilesCount, CurrentFileName, TimeElapsed, TimeEstimated, TransferSpeed"

Skin="Vista">

</telerik:RadProgressArea>

</td>

</tr>

[Solved] Close Radwindow with button in ContentTemplate

Hi,

I'm trying to close a RadWindow using a button defined in the RadWindow's ContentTemplate, but I'm having trouble getting a reference to the RadWindow object using my GetWindow() javascript function. It's the same GetWindow function that I use in other RadWindows (and that's used in various Telerik examples) and it works fine, except in those scenarios I'm using the NavigateURL property instead of ContentTemplate.

I'm using Firefox right now, so I expect the first part of the if-clause in the GetWindow() function to execute, but instead it drops down into the else-clause and then I get a frameElement is null error (since it's Firefox I assume.) But really the first part of the if-clause should be executing.

Here is a sample:

Thanks for your help, -Scott

ASP:

[Solved] Button inside RadInput

I am trying to create a search input with the button inside of it, just like the search box in the www.microsoft.com page. I got the code from this page to do this.
http://www.telerik.com/community/code-library/aspnet-ajax/input/how-to-create-a-button-inside-a-radtextbox-ui.aspx

I am using my own custom theme for the telerik controls, including RadInput. My one-of-a-kind textbox I need for search does not come up the way I want it, it takes all its look from the telerik theme.

Thanks for any help.

Issue with adding OnDateSelected client event

Hello,

My script references start erroring across the board whenever I add a date selected client-side event handler in the callback, as in:

<%= Html.RenderRadDatePicker((rad) =>

{

rad.ID = "StartDate";

rad.SelectedDate = DateTime.Today;

//rad.ClientEvents.OnDateSelected = "StartDate_DateSelected";

}, "Forest") %>

<%= Html.RenderRadTimePicker((rad) =>

{

rad.ID = "StartTime";

rad.SelectedDate = DateTime.Now.RoundHoursUp(1);

//rad.ClientEvents.OnDateSelected = "StartTime_DateSelected";

}, "Forest") %>

WHen the event handlers (with comment // removed of course), the page goes crazy with errors. What is the cause of this? Missing a script definition?

Thanks.

Setting RADEditor to headings only

Currently we are using the RADEditor in a Content Management System for allowing users to add/update news articles for their websites. This gives the user a great amount of flexibility to for adding images, documents. etc to the news articles. Currenly each news article contains a heading and summary for displaying news in a simple list with a read article link for retrieving the complete article. The heading and summary fields are standard asp:TextBox controls.

The latest request has been to provide an option for linking the heading to a PDF file as well as attach a thumbnail image to the heading. Since the RADEditor already provides for this I was going to use a very basic toolbar that only displays the ImageManager and LinkManager button to allow users to add this to the heading.

What I would like to know is if it would be possible to set the default tag for the Editor to a heading tag as this should be the only option for our news headings?
