My guess this is in a callback grid. There is currently an issue with the combobox, which is that the Grid isn't re-initializing these combos. One thing to do would be on Callback Complete client event, initiailze the combobox. < script > function Grid1_onCallbackComplete(sender, e) { ComboBox1.Initialize(); ComboBox1.Initialize(); } </ script > ...this is correct, we initialize twice... < componentart : Grid ... > < ClientEvents > < callbackcomplete eventhandler =...

As a developer, I should not have to waste my time digging for knowledgebase and forum issues if you already know about them.
I should be able to look at the Callback demos, for instance, and not have to search the web to find out that I need to dispose of my grid:
This demo:

...should be updated with this KB info:

Hi,
When using grid in callback mode, I will be returning records ONLY for current page.
So first time when grid is shown, proably I will be showing Page 1.
How do I set total number of pages, so that user knowns how many pages of data is available.
I understand PageSize and sending page index, size to server. But I could not find DataGrid property that sets total pages - so that user can browser through pages -Even thugh he sees only one page at a time.
Thanks

Ho, this one is bugging me quite some time.
I have a gridview inside a CA callback. This code is located in a composite user control. When the callback fires the callback handler stores some variables in the viewstate of the user control. So far so good. But when the NeedDataSource event of the Grid fires the Viewstate has been cleared.
Can someone provide some hints why this is the case ?
Many Thanx,
Marc.

Hi, I am having a problem with the snap control. What I am trying to do is create a sort of portal that contains user controls.
On the server, the user controls are loaded, and placed into a snap control that is created server side. This all works fine, the snap controls all get generated and apeear on screen. However, some of the user controls contain controls that require callbacks to function (A third party datagrid being one).
Now for some reason these callbacks do not function while they...

This is my sample of a fully database driven Treeview. Notes : Client Treeview with client events: <NodeBeforeMove EventHandler="onBeforeMove" /> <NodeMove EventHandler="onMove" /> <NodeRename EventHandler="onBeforeRename" /> <ContextMenu EventHandler="TreeView1_onContextMenu" /> <CallbackComplete EventHandler="TV_onComplete" /> Database actions are performed using component are callback Extra client actions are suppressed...
