Hi,

I want to implement an interface with 2 RadGrid's with a plitter between them to give an 'Explorer' like view.  When the user clicks on a row in the left hand grid it identifies the item being clicked and will re-display the right hand grid to show details of the item selected.  I would have thought that this would be trivial but I can't seem to get it to work.

I have captured the SelectedIndexChanged event for the LH grid but when I look at the gridParts.SelectedItems[0].DataItem value it is always NULL which I am not sure why.

Any-one got an example of using 2 grids in this way?

I want to add "Print" option in CommandItemSettings along with existing Export Options. Is there a way I can extend CommandItemSettings, or do I need to create my own CommandItemTemplate?

My company has a project that runs on a 2.0 .net framework app pool.  This project consumes a 2009.3.1208.35 versioned Telerik DLL.  Telerik.Web.UI.  I am trying to track back and find the documentation for this version of Telerik.  Can your group help me to locate the documentation for this code library?

Thanks!!!

Hi,

I was showing an expand/collapse all button in the grid using the code smaple in:
 http://www.telerik.com/community/code-library/aspnet-ajax/grid/custom-expand-collapse-column-with-expandall-collapseall-image-button-in-the-header.aspx

However, I am unable to remove the default expand collapse column. I used the solution given in the thread but that does not work for me. It changes the alignment of my grid when it is expanded.
Can you tell me how to hide the default column.

Hello
as I can put the format "year - month - day hour:minute:second" in datatimepicker?.

thank you very much beforehand

Hello, 

I have a column 

 <telerik:GridButtonColumn CommandName="SELECT" Text="SELECT" 
                        UniqueName="Select" >
 </telerik:GridButtonColumn>

in a radgrid, and I have the radgrid property 

onitemcommand="ItemCommand"

But when the button is clicked the event does not fire. Any ideas? I am on a deadline fast coming and this has stopped me in my tracks

All I could find in my searches is that I need to enable viewstate, but that has had no effect. 

I'm dealing with quite large datasets here, and my application seems to throw an IO timeout exception if i set ignorepaging to true and there's too much data.

So what i've done is created a hiddenfield for my total record count and i want to limit the number of records exported to 500, in the hope this will avert said exception, see below:,


However this doesn't work. I'm assuming because the pagesize has already been set to 20, thus only 20 records are being exported.

Is there a way i can achieve the above results or are there any other suggestions you'd recommend?

I have, I believe, followed the examples correctly, but every time I try to Export to PDF  the entire table opens in the current window.


I expect to get all the data and I do, If I change the "IgnorePaging" to false I just get the first page, as I would expect. But changing the value of OpenInNewWindow has no observable effect.

I am obviously missing something very simple, but I just can 't see it. Any ideas?

Am having truoble with my autogenerated edit form after posting back the if an EntityDataSourceValidationException is thrown.  I am overriding the Entity DataSource Inserting Event and using automatic inserts on the grid. 

The first time the exception is thrown the drop downs in my edit form retain their values and I am able to insert the values after correcting the errors on the form.

However, if I try to insert again without correcting the validation errors, after postback the values in the drop down lists are lost and the edit form is then unusable.

Hoping to hear if this the right way to do this, or if I need to just allow the grid to auto insert withough overriding the Entity Data Source Inserting Event.

I am providing the grid code, entity data source and the code for the inserting event.


Thanks!

We have a RadListview which is binding to a DataSource control and have item, edit and insert templates.
The datasource control takes care of selecting the object when the page loads and does the data bind.  The datasource control (actually a CslaDataSource control) binds to our business layer objects which are enumerable, and we just show one "record" in the listview.
Really we are making use of the templating to show display, edit and insert modes for our record/object.

We also tend to have our own user controls also in the templates and pass the business object down to them so they can bind to their respective controls.

All works well.

Except we have one slight issue.  When inserting a new record and attempting a save, the datasource control xxx_Update method gets fired and if the business object throws an error (typically as some business rule is broken and it cannot be saved yet), the RowsAffected is zero and we set a PageHasErrors flag.

The page posts back and in our Page_PreRender event we try and switch the listview back into Insert mode as we want to keep it there in that template as the save failed.  Unfortunately this doesn't quite work as we end up with the display item template shown first and then the insert template below.

It almost looks like it has created 2 records in the listview.

Any ideas?
