Hi

I am using RadGrid With Paging(Mode:NextPrevAndNumeric).

Issue:-

The Problem is when i change the Page Size From the dropdown Let's say 2 to 10. then there is no record Display even the Grid has 5 records.

This Problems has Come after I implemented the "expand/collapse images when no records" in the grid followed your tetelrik article.

If I do the, Hieararchy Load Mode="Server" or remove "expand/collapse images when no records" behaviour then it's works fine.

But I need Both feature..

I also Attached the Code and Images

 

Please Provide The Solution ASAP.

Thanks & Regards

I am trying to get the Demo code working in my project with the Grid / Scheduler drag and drop demo and I am getting an error from the java-script function rowDropping. This line is throwing the error:


The error I get is: "Microsoft JScript runtime error: Unable to set value of the property 'value' : object is null or undefined"

I am not sure what I am missing, I have looked through the demo code several times.

Thanks!

Hi there

Can anyone point me in the right direction with a problem that has so far stumped me? I have a RadTreeView that uses an .ascx User Control as its node template, and which displays data from a hierarchical data source - the data is a hierarchical set of 'comments' submitted by users for a blog post. All this works fine. The issue is, I am trying to work out the best way of dynamically incorporating into a node an editor control which would be displayed ONLY if a new comment needed to be added as a 'reply' to an existing comment. In other words, I'm looking for a way to only display a text area editor in a node if the 'Reply' button is pressed for a particular node. Obviously I could have a RadEditor hidden within each node template, to be shown only as and when the Reply button is pressed. BUT ... this would mean having a RadEditor control for each and every node in the treeview, and I'm pretty sure this would have rather severe performance implications. I have many many nodes, and dread to think how slow it would be to have a RadEditor control instantiated server-side for each and every node.

At the moment I just have a single RadEditor outside the treeview hierarchy, but this is not ideal as it means the reply text area is at a different place on the page to the comment in question to which the reply is being made. Instead I'm looking for a way to do something like the review pages of Amazon, which appear to re-use a single control at different positions in the comment hierarchy dynamically on demand - I haven't really managed to reverse engineer their technique yet, it seems quite complex, but it appears to involve having a single 'pre-rendered' text area/editor hidden on the page, which is then dynamically injected into the tree view at the correct location by client-side Javascript, using a Placeholder that IS already included in the node template they use (I appreciate they may well not be using the RadTreeView control, but it is something similiar). 

So my question is, are there any additional RadControls that I should be using in order to reproduce this behaviour, or what would be the recommended technique for dynamically re-using and repositioning a single editor control within the tree view hierarchy as a whole, in a way that would avoid having a RadEditor control instantiated for every single node.

Thanks very much for your advice.

Hi,

I am having a radgrid with template columns containing checkboxes and radcombos . And the last  template column is having a radcombobox control.

On client click of checkboxes, if  checkbox is checked radcombo should be enabled , else it should be disabled.
I want to achieve this functionality by using javascript.
Any suggestions or sample code please help..


Thanks & Regards,

Hi,

 I have a simple problem but have been having a frustrating time figuring this out. I have a html table which has two rows 'trExistingCustomer' and 'trNewCustomer'. I have an edit popup form on the grid. I want to show a certain row and hide the other based on what command the grid is trying to do (Inset / Edit). I use Jquery in a RadCodeBlack to do this, I am firing a function on the ClientEvent OnPopUpShowing. how I can I check if this was triggered from Insert comand or Edit command in the javascript. I already tried using the function onCommand (Please see code) I saw another example and thought this might be the relevant function but this is not working and it displays all rows. Can someone please show an example in code how to check for the calling command in the popup function or onCommand to do this right? Also is there a list of all client side events asscociated with the edit form and the grid somewhere, I think that would be helpful to know. Any help is appreciated

Hello!

I'm having some serious issues with RadComboBox which behaves erratically. The problem is I can't bind the data from ItemDataBound event of the RadGrid to the RadComboBox that is inside the UserControl. I always get errors that there is something wrong with binding even though it should work properly.

Here are the code snippets:

The problem occurs in the line with RadComboBox rcbAsset. The problem is a bit urgent so any help would be appreciated!

Hi,
I have a scheduler that is initially hidden on my page.  After the user hits a button the data should be populated.

Technically it works fine and the data is shown BUT on the first load the height of the scheduler is normally set to about 108px.  I've hardcoded the height to be 550px and that doesn't fix this.  

Interestingly if I resize the page, reload the page, visit another page and then come back the problem doesn't reappear until the tab is closed and a new tab opened. This seems to be affecting all browsers but is most demonstrable in chrome and is easy to replicate in chrome.

Tomorrow I'll be creating a demo to solve this, in the meantime is there any obvious reason why this might be happening?

Regards,

Jon
