Can we limit the amount of callbacks when EnableLoadOnDemand and MarkFirstMatch=true?

I have a RadComboBox with EnableLoadOnDemand=true with an ItemsRequested event that fires when you type any character into the combobox text field. This all works, but it is too slow because of all the callbacks after every character is entered. Let's take this example:

I am looking for the value 1422 in my combobox list. I type '1' and it calls the server and shows me all items that start with '1'. Then I type '4' and it calls the server again to show me all items that start with '14'. This seems unnecessary. If we already have a list of all items that start with '1', then why do we need to call the server again to get the subset that starts with '14'? After the initial results are returned to the client, can I somehow search those results on the client for the '14' entries. After all, they have already been sent from the server, there's no need for any additional callbacks unless I delete back past the '1'.

Any help would be much appreciated.

thanks!

GridNumericColumn format

I think there is a bug regarding GridNumericColumn and formatting. I use currency format as follows: {0:#,##0;(#,##0);0} .
In the view mode column looks OK. The problem is when the row/item is in edit mode and yet the column is readonly.
If the column is readonly, I should see the same formatting as in the view mode. Is this a bug?

I see a lot of threads on the same topic and yet could not find definite answer from TELERIK on the topic.
Is there a manual fix?

[Solved] Problem in SlidingPaneDock?

Hi,

I created as RadSlider as below

<telerik:RadSplitter ID="RadS_Filter" runat="server" Height="22px"
Orientation="Horizontal" Width="820px">
<telerik:RadPane ID="RadP_Filter" runat="server" Height="22px" Scrolling="none">
<telerik:RadSlidingZone ID="RadSZ_Filter" runat="server" Height="22px"
SlideDirection="Bottom" Font-Size="Medium" Width="500px">
<telerik:RadSlidingPane ID="RadSP_Filter" runat="server"
BackColor="ButtonFace" Title="Filter" Height="120" OnClientDocked="changesizefilter" OnClientUndocked="ChangeUndockSizeFilter">
<table cellspacing="10" id="tbl_comboTable" runat="server">
<tr>
<td>
<asp:Label ID="lbl_FilParent" runat="server" Text="Parent"></asp:Label>
</td>
<td>
<telerik:RadComboBox ID="RadcmbFil_Parent" runat="server" AutoPostBack="True" AllowCustomText="True" onselectedindexchanged="RadcmbFil_Parent_SelectedIndexChanged" Width="300">
</telerik:RadComboBox>
</td>
<td>
<asp:Label ID="lbl_FilStudent" runat="server" Text="Student"></asp:Label>
</td>
<td>
<telerik:RadComboBox ID="RadcmbFil_Student" runat="server" Skin="Hay" AllowCustomText="True" Height="22px" Width="300">
</telerik:RadComboBox>
</td>
</tr>
<tr>
<td>
<asp:Label ID="lbl_FilSubject" runat="server" Text="Subject"></asp:Label>
</td>
<td>
<telerik:RadComboBox ID="RadcmbFil_subject" runat="server" AutoPostBack="True" AllowCustomText="True" Width="300">
</telerik:RadComboBox>
    </td>
    <td colspan="2">
            <asp:Button ID="btn_FilterSearch" runat="server" Text="Search" Width="100" />
    </td>
    </tr>
            </table>
</telerik:RadSlidingPane>
</telerik:RadSlidingZone>
</telerik:RadPane>
</telerik:RadSplitter>

After this i used two Java script Functions for ClientDocked and Undocked

When the client Docks

function changesizefilter()
{
var splitter = $find("<%=RadS_Filter.ClientID%>");
var height = 150;
splitter.set_height(height);
__doPostBack('<UpdatePanel>',');
}

When The Click Undocks

function ChangeUndockSizeFilter()
{
var splitter = $find("<%=RadS_Filter.ClientID%>");
var height = 22;
splitter.set_height(height);
window.location.reload(true);
}

But the problem is getting at onclientDocked.
when the client docks the page is refreshing Multiple Times......Why it is happening..Does it acheives in other way?
Regards
Bhuvan

GridClientSelectColumn select all

Hi all,

is there a way of manage (via code behind) the checkbox in the header that comes with a GridClientSelectColumn?
I couldn't find the right way. I also tried to manage it via an event but it doesn't fire.
Here's a snippet:

...code
GridHeaderItem headerItem = (GridHeaderItem)RadGridDocumentsControlForm.MasterTableView.GetItems(GridItemType.Header)[0];
CheckBox chkSelectAll = headerItem.FindControl("CheckedSelectCheckBox") as CheckBox;
chkSelectAll.Enabled = true;
chkSelectAll.CheckedChanged +=new EventHandler(chkSelectAll_CheckedChanged);
...code

//handler
void chkSelectAll_CheckedChanged(object sender, EventArgs e)
{
//code
}

Thanks in advance.
