Hi,

I have a simple two table grid hierarchy. I want to do totals on the detail table in code behind. Samples found elsewhere on this site indicate that in ItemDataBound, we can do this, but this line never evaluates to True even though ShowFooter="True" is set for both the Master and Detail Tables. What Am I missing here?

  If TypeOf e.Item Is GridFooterItem Then

We are using the 2008.1.619.20 version of the Telerik ASP.NET AJAX Controls. We have been getting the following errors on our page that uses the telerik treeview control.

Exception Type:        System.Web.UI.ViewStateException
Exception Message:     Invalid viewstate.


Exception Message:     Unable to validate data.
Exception Source:      System.Web
Exception Target Site: GetDecodedData

Exception Type:        System.Web.HttpException
Exception Message:     The client disconnected.

After doing some research and also searching the telerik forum we set enableViewStateMac="false" and viewStateEncryptionMode="Never" in the web.config file. We also set the maxRequestLength="10000"  for the httpruntime but nothing has helped us with the errors so far. I will greatly appreciate if you help us resolve this issue at the earliest.

Thanks

Hi all

I am getting an error on my page when I try to load a popup window and have been trying for several days resolve this issue.

I have three hierarchy grids on my page one contains a grid binary image column.

Here is my code

 

Code behind for displaying images

 

 

Here is the issue:

Grid one (rgListings) has a Preview link in one of the columns which I use to open a new window through some javascript which is in a file on my project. When I add a listing into this grid and I click on the Preview link in the row the window pops open no problem.

But when I add a listing in the rgListings grid and then add an image in the second (rgSlides) grid that is where it comes to a halt. When I click on the Preview link in the rgListings grid to open the pop up window I get an object not found error and I do not know where to look. I think that I have pin pointed it to this javascript on in the markup, but I am not sure.

I think this is where the error is comming from, but not sure:

 

 

I have tried putting some jscript on the page to open the window with the btnPreview.Add.Attributes(“onclick”,  “showForm();”) which does open the pop up window but I still get that object not found error and 2 windows open. I also added a button in the grid in the item template and called the jscript window open using the OnClientClick which opens the window but I still get the object not found.

Hopefully some extra eyes might see my problem.

Hi, I would like to know if it is possible to resize a column depending the length on the content.

For example, I have a product that uses several dynamic fields with contents ranging from 1 character up to (think free-text).

Here's the code I use to generate all fields:

Hey all,

I have been very busy lately working on a new project that uses MVP. We are plugging along and everything was going very nicely until we got to our event viewer page in our admin menu. We are using a custom implementation of the standard .NET 2.0 web event schema that we built using the MVP pattern. I want to use a RadGrid for the main display because it is a nice package for our requirements (toggle, click to expand, etc). This brings me to the problem. With MVP, the user interface is extremely thin. We built the classes and code using TDD best practices, and unfortunately, we didn't do our homework on the RadGrid very well. We mistakenly counted the NeedDataSource event as a standard EventHandler (like most other event delegates that perform data binding). What could we do to resolve this problem? Keep in mind that the obvious solution (adding the Telerik.Web.UI reference to my presenter, and model projects) is absolutely out of the question.

View Interface

Presenter Class

Here is where things go sideways. I get the following error in the code below. Cannot implicitly convert type 'System.EventHandler' to 'Telerik.Web.UI.GridNeedDataSourceEventHandler'.

I am having trouble figuring out how to solve this without breaking the rules for MVP.

I love these engineering challenges, but this one has me pretty well stumped.

Any Thoughts?

Thanks,

John

Hi,

The stylebuilder has some great promise.  I headed in to customise my most used control, the chart, and it isn't present yet.  Is it in the plans?

Thanks!
