Hi

I have rad treeview with check box and my treeview have more than 2000 nodes.
Top of the treeview control i have a check box check all. when i click the check all checkbox i need to select all the parent and child nodes. With out looping the node, is any other option is there?
Because if i loop all the node using javascript, IE giving the error message. script is running continuously it will slow down other operations.

Regards

Group header - change boolean to something more meaningful

I have RadGrid with grouping enabled on boolean field. The thing is, group header contains field value True or False, which I'd like to change to something like Yes or No.

I know I could alternate the text on ItemDataBound event, but that is not very flexible - it will always change True/False to Yes/No, even when there will be actual need to display True/False.

Are there any aleternative approaches for changing group header text?

RADCombobox Multiple Parameters

Hi,

I am using autocomplete for a RADCombobox.

[OperationContract]
public RadComboBoxData wpfSelectProgrammeFromClientDB(RadComboBoxContext context)
{
}

In this service, I am using a SQL Query to fill a datatable.

strSQLQuery = "SELECT pk_ProgrammeID,Title FROM Programme WHERE Title LIKE @prefixText";
da = new SqlDataAdapter(strSQLQuery, ConfigurationManager.ConnectionStrings["DEMO"].ToString());
da.SelectCommand.Parameters.Add("@prefixText", SqlDbType.VarChar, 50).Value = "%" + context.Text + "%";
dt = new DataTable();
da.Fill(dt);

In my .aspx, I use

<telerik:RadComboBox ID="rcbClientProgrammeTitle" Runat="server" EmptyMessage="Select a Title" EnableLoadOnDemand="true"
ShowMoreResultsBox="true" EnableVirtualScrolling="true" Skin="Windows7"
AutoPostBack="True" >
<WebServiceSettings Method="SelectProgrammeFromClientDB" Path="LinkMedia.aspx.cs"/>
</telerik:RadComboBox>

I need to pass a second parameter to the SQL Query, like

strSQLQuery = "SELECT pk_ProgrammeID,Title FROM Programme WHERE Title LIKE @prefixText AND Client = @Client";
da = new SqlDataAdapter(strSQLQuery, ConfigurationManager.ConnectionStrings["DEMO"].ToString());
da.SelectCommand.Parameters.Add("@prefixText", SqlDbType.VarChar, 50).Value = "%" + context.Text + "%";
da.SelectCommand.Parameters.Add("@Client", SqlDbType.VarChar, 50).Value = " + WHAT DO I PASS HERE;
dt = new DataTable();
da.Fill(dt);

OR is there any other alternative to do this. The @Client comes from a Query String which I am not able to access in the WCF Service.

Can you please show me a demo of how to send multiple parameters to the Service or how to access the query string values from the page in the service.

Thanks
Prithvi

Rad Editor Backspace Deletes Entire Paragraph

Pressing the backspace in Google Chrome after certain character combinations deletes the entire paragraph. I can reproduce this by pasting the following HTML:

<p>x 5 1/2 x</p>

Note, there are two spaces after the 1/2. If I switch back to HTML mode, position the cursor key just after the 2, and hit backspace, the entire paragraph is deleted. I can reproduce this in the Telerik demo here:

How to get SeriesItem name on drill down?

Hello all,

I'm learning to use the RadChart control and I'd like to ask how to dynamically get the name of the series item that generated the RadChart.Click event to use it as part of the series name for the next chart generated (ex. if the chart shows the sales volumes per month in an given year and the user clicks on the July column, the next chart should show the details for July and the series name would be "Sales details for July").

Any help would be really appreciated!

Error before page load in javascript

Hi,
I am using Telerik RAD controls(RAD Combo, RAD TextBox ,RAD Tab etc) inside update panel. It was working fine just a few days back. Now I am getting error "Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: id" before page load. I am using VS2010, framework 4.0 with Win-XP. It is always occurring on a single page while others are working fine. I matched Telerik version from Web.config and in Reference added (not using GAC here). I'd also added AJAXToolkit dll and added in reference of project. I also tried with removing Update Panel but got same result.

Problem with custom column an

Hi,

I have a custom column (who's inheriting from GridBoundColumn) who display an image related to the DataField. I override the method InitializeCell :

public override void InitializeCell(TableCell cell, int columnIndex, GridItem inItem)

when the page load for the first time, the parameter inItem.DataItem is not null and contains the object representing a row from the DataSource.

On the other side, in the PostBack, inItem.DataItem is null ! So I can't retrieve my data...

Is something wrong ?

Thank you !

enter key on selected command button in command bar saves record instead of fires command

Hi,
I have a radgrid with a custom command bar (commanditemtemplate) with a few linkbuttons on it.
Also I have the radgrid ClientSettings AllowKeyboardNavigation="true" and KeyboardNavigationSettings AllowSubmitOnEnter="true"
When I move to the command bar with the TAB key and select a linkbutton (or use the associated AccessKey to select it immedeately), then use the ENTER key to fire the button, instead the selected record is opened for editing.
How can I skip the SubmitOnEnter when I have the linkbutton selected?

I tried the code below, it gets fired when the enter key is pressed, but still the record is selected instead of the command fired.
Any ideas?

Thanx in advance,

Regards,
Frank

Telerik.Web.UI.RadGrid.prototype._canHandleKeyboardAction = function (e) {

var keyCode = e.keyCode || e.charCode;

if ((keyCode == 32 || keyCode == 13)

&& this.ClientSettings.KeyboardNavigationSettings.EnableKeyboardShortcuts) {

var target = Telerik.Web.UI.Grid.GetCurrentElement(e);

if (target.tagName.toLowerCase() == "a") {

return false;

}

return true;

}
