hi,
i have a RadListBox in a GridTemplateColum with a different datasorce of radgrid.

can I apply filter on this column? 

Hi all,

Hello all

I've been diagnosing a problem with a grid control being slow to respond to user input for a sister company.  This is using the trial version of 2012 Q1 (this sister company does have a license, but I don't have access so installed the trial version).

Row selection in a grid with just over a 1000 rows in now quicker, but it still too laggy (taking about 0.2 seconds for selection to change).  This software generates grids on the fly from user designs in the database, and the grids can be quite complex with check boxes and drop down lists in the table elements, which if there are a number of controls on there seems to slow everything down to a crawl (which to be fair I'd sort of expect, with a DOM with 20,000 drop down lists in it).

I was just wondering if there is a suggested maximum number of rows to populate in a grid?  Is paging always recommended to make the control act in a controllable manner disregarding the number of rows it has to display?

Cheers.

Hello,

I am currently replacing all our classic grids using the new ajaxGrid. Many of those pages bind the data inside the Page_Load.
But i noticed that does break the pager when using the new ajaxGrid. The back and forward buttons aren't working anymore.

I kinda need this to work, since its a no-go to change all the code to get this working. I did include a test project that i made to be sure this really is the cause of the problem.

Please help me, since i've been on this for a while.

Kind regards,

Guido

this is the test project (till Apr 19 / 2012)

In My application I populate Nested Rad Grid with three nested tables:
<clients>
<matters>
<files>
</files>
</matters>
</clients

On each level there is a RadioButtonList with three buttons Approve, Assign, Forbid
There are two problems.
How do I populate the Radio Button lists on every level?
What event populates data in the nested views?
Seems easy on the main level, but I cannot make it work on the levels down:

 Protected Sub rgSessionClientsNested_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgSessionClientsNested.ItemDataBound
If e.Item.ItemType = GridItemType.AlternatingItem Or e.Item.ItemType = GridItemType.Item Then
Dim dataItem As GridDataItem = e.Item
Dim radCell As Telerik.Web.UI.GridTableCell = dataItem("authorize")
Dim forbidCell As GridTableCell = dataItem("forbidCnt")
Dim state As String = forbidCell.Text
Dim rdList As System.Web.UI.WebControls.RadioButtonList = radCell.FindControl("RadioButtonListClient1")
If state = "A" Then
rdList.Items(0).Selected = True
ElseIf state = "F" Then
rdList.Items(1).Selected = True
ElseIf state = "N" Then
rdList.Items(2).Selected = True
End If

Second question is related to the first one.
When the user clicks a button on any level I need to trigger a database update.
How can I do it?

Thanks in advance!

Hi, is it possible to update data binded to a chart within the chart itself ?

If, for eaxample, I've a line chart , I wanna "drag" a point showed in the chart and change the binded data value

Thanks

Hi,
I'm using a GridDropDownColumn in a RadGrid. It loads fine and works fine, until I add ajax on the grid.
The reason for the ajax is that I need to reload the grid after a RadWindow has closed. I rebind the grid and need it to reload.

The manager looks like this:

The text fields in edit mode work fine but the dropdown column is disabled. I can select the text in the box but not do anything else.
I've been hitting a wall all day and could use some fresh ideas.

I would like to use the XmlHttpPanel to display some content and I am trying to minimise server load.

I have a set of imagebuttons within a repeater control. Its the first time I've used the XmlHttpPanel. The XmlHttpPanel displays information from a specific database record defined by InfoId. I can set the repeater datasource with information containing InfoId. I could set the commandArgument for the buttons to  '<%# Eval("InfoId") %>' but that would then involve a postback to execute an OnCommand event. I therefore assume that it would be more efficient (a little like the First Look example in the demos) to have the imagebutton OnClientClick execute a javascript function that then sets the XmlHttpPanel value to the correct InfoId and the panel can then get the required information.

I have two questions: (1) am I write that dealing with the button click in javascript rather than a command postback would be more efficient and (2) that being the case can someone help me with how to set the OnClientClick property of the imagebutton in the repeater. I keep getting messages that the tag isn't well formed or some other error.

I'm assuming that the following javascript is fine (and it works if I hard code the OnClientClick property for a button):

<script type="text/javascript">

 function myClientClick(index)

 {
var myControl = $find("<%= myXmlHttpPanel.ClientID %>");

 

myControl.set_value(index);

return false;

}
</script>

However, to make this work I need the OnClientClick property to be of the form: "return OnAdditionalSelect('x')" where x is the InfoId. If I use Eval("InfoId") I get errors and putting \' to try to get the single quotes around the id also causes a "tag not well formed" error.

 

I am having some challenges trying to embed a RadGrid within a RadListBox.  Do I have to do a FindControl with OnItemDatabound?  Or can I do it on Page_Load()?  Any help or point me in the right direction would be greatly appreciated.
