I have used RadWindow many times and have always been able to do a close and rebind. This time however things are a little different. To rebind the data to a radgrid I need to call a SQL stored procedure.

I have all the Javascript and Ajax code set just like the online example. This usually works. The typical Ajax Request Handler looks like:


This works when the radgrid is bound to a SQLDataSource. However, I need to rebind the grid using:


I tried to modify the handler to call my function but this does not work:


Any help performing a RadWindow Close and Rebind.

I would like to remove the "Select All" checkbox from the header, and add an expand all button to the header above the "+" icons.  What is the best way to do this?  There doesn't seem to be a "header template" for this control.

Hello,

I have seen this topic in many different forum posts and demos on the site and I have tried so many different things I am just totally confused about how to make this work.

I have a RadGrid in which I am doing Inserts and Updates through an ObjectDataSource.  In the FormTemplate among other controls I have two dropdownlists that are both populated by their own ObjectDataSources.  The SelectParameter of the second dropdownlist is the selectedvalue from the first dropdownlist.  Before I converted this page into a RadGrid I simply used a ControlParameter for the ObjectDataSource of the second dropdownlist referencing the first one.  Now it seems that I can't do that within the FormTemplate of the grid for multiple reasons.

So what I need to accomplish is the following:

1.  I want the dropdowns to show the correct item as selected when that item is "edited".
2.  I want the second dropdown to be repopulated with the correct items when the first dropdown is changed.
3.  I want the correct item saved to the database on insert and update.

These are pretty obvious but at this point I'm not sure what I need to do to make that happen.

Here is the important snippet of my aspx code:


So on an edit/update command this works.  It displays the correct item as selected in the second dropdownlist.  I am fine here because I actually set enable=false on an edit because they are not allowed to edit that field so I don't have to worry about changing the first dropdownlist and repopulating the second.

But the problem is on an insert.  When I try to add a new entry I immediately get an error that the second dropdownlist has a SelectedValue that is invalid because it doesn't exist in the list of items.

Maybe this is because I am setting the default empty value (or in my case 0)?

Here are the important parts of my codebehind:


I had tried moving the populating of the second dropdown to the SelectedIndexChanged of the first dropdownlist (as you see commented out) but that causes the problem that when it tries to save it doesn't save the item to the database because I had to remove the SelectedValue='<%# Bind("Position_ID") %>' for the aspx page because of another error.

Someone please help me to figure out the best way to accomplish this.  Do I need to do the entire thing in code including the insert/update tot he database instead of letting the grid do it?

thanks,

Steve

I took the code to have a treeview in a combobox and it works fine. Problem is, I need it to do an autopostback when somebody changes the value. I have put autopostback=true for the combobox (there isn't one for the treeview) and it works when you first come in and there's no value for the text in the combo box. But once it's been set, it doesn't do the autopostback.

Any thoughts?

TIA - Jeff.

I'm creating a grid dynamically based on filters the user provides. The issue(s) I'm having are:

1. The column filters no longer work. That is, selecting "Contains" or "StartsWith" doesn't work.
2. When going to page 2 of the grid, all records are returned (looks like the grid is rebinding and is bringing back every record in the db instead of filters the dataset that's already contained in the grid)

I have a radgrid which I am binding in the server side using the needdatasource event. After the initial bind, I need to refresh the grid once every 10 seconds. I need to refresh the grid only if the data has changed since the previous bind.

I have these lines of code in my javascript.



This fires up the need datasource event of the grid. Is there a way I can bind the grid conditionally in the needdatasource event ?
If the data hasn't changed then I want to skip the refreshing of the grid and retain the previously bound content. Following conditional binding of the grid throws error in some of the GridTemplateBound columns.



I know that I can check if the data has changed by making a wcf call from client side. I really wanted to avoid making multiple calls to get the data/ check for data.

I have a radgrid with some hyperlink columns, and a contextmenu atteched. is there any way to keep the browser menu when right clicking on hyperlinks, keeping the contextmenu on "other" row right click renderings?

here´s my grid code if its to any help.

I have a radgrid which is using GridTemplateColumn to enable me to manage the content the way I want.  The Grid worked when i was using GridBoundColumns but when i switch i'm getting the following error.

"exhibition with ID 4 cannot be updated. Reason: Cannot insert the value NULL into column 'exhibitionTitle', table 'trevorbollenart.dbo.exhibitions'; column does not allow nulls. UPDATE fails. The statement has been terminated."

All the controls have been filled in (including exhibitionTitle) does anyone have any ideas? I'm guessing I can mix and match GridTemplateColumn and GridBoundColumns?


Code show below.

This is Carlos Mendoza from Accenture, US.

I’m not sure if this is also the same email address for requesting technical assistance so I’d appreciate it if you just forward to the correct group if so.

Our project purchased Telerik’s HTML editor product, and implemented it on our corporate web site, www.accenture.com

That web site is built on MOSS 2007. We have another web site, microsite.accenture.com, built in MOSS 2007 too, in which Telerik’s HTML editor is implemented in there too.

On the Microsite web site, Telerik’s toolbar is able to retrieve the site’s alternate CSS file (.css), and display the CSS classes defined inside the CSS file on the Style dropdown of Telerik’s toolbar, so they can be used by our end users. See attached screenshot below.

 

 

 

 

 

 

 

 

On the www.accenture.com web site, this is not happening on Telerik’s Style dropdown section.

Our clients would like the same behavior of the Style dropdown as the Microsites web site. Is there any configuration or line of code we should implement on the www.accenture.com platform so additional CSS classes defined on the site’s alternate CSS would appear on the Style dropdown of Telerik’s HTML editor toolbar?

 

Please advise.

 

I’d be glad to hop into a call if needed. Just tell me the telephone number of your technical support team.

 

Looking forward to hearing from you!

Hello,

I am using the Popup Edit Forms with my RadGrid.  When I set the MasterTableView.EditFormSettings.CaptionFormatString to some string, the Popup window appears with two titles that say the same thing: the title of the window, and a form title below the window's title.  Both captions say the same thing...

I would like to remove the form title but leave the Popup window title... Is that possible??

Thanx,
Manuel
