Hello

I have a dropdowntree that is updated using a treelist.

I wish when I check a line in my treelist check the corresponding value in the dropdowntree.
But also uncheck the old value.

I use this for

dropdowntree.get_entries().clear()

This method works the first time but if I check a value a second time it no longer works.

I have that :
Dropdowntree.get_entries().count() = 0

Adding classes to the Lists command

I would like to apply a class on the <tool name="InsertUnorderedList" /> , <tool name="InsertOrderedList" />

Is there a way to subscribe to tool events to apply the classes when working with the tools.xml? We are using the Rad Editor for content blocks and would like to apply classes according on the ul and ol tags.

If we are to use JS function where would the JS file be located to be available to subscribe to the events fired by Rad Editor

Overriding InsertUnorderedList

Is there anyway I can override the InsertUnorderedList command's value to add a class of "mainlist" to the <ul> tag?

Our designer has set the css up so that the only unordered lists that get bullets are <ul>'s with that class.

Is there anyway I can change the value of the HTML that is about to get inserted before it gets inserted? I don't want to change any of the logic of the insert, just the HTML.

Thanks.

Rebind gives error : 'There was a problem extracting DataKeyValues from the DataSource.' on Rebind

Hi,

I am using a RadGrid with DetailTables.
I am using inline editing for each of my DetailTables.
I am able to perform Insert/Update operations. However, after the inert or update operation when I call Rebind on the RadGrid, I get the folowing error : There was a problem extracting DataKeyValues from the DataSource.
This message is displayed in Visual Studio in the catch block. However on the error page it says "

COLUMN_NAME is neither a DataColumn nor a DataRelation for table Table.

". I have data in my table. This error does not show up when the page loads normally. It only shows up when the Insert/Update event for the RadGrids DetailTable is fired.

Could someone provide a solution and tell me the reason why this is happening.

Thanks,

Grid

Can't get selected items on server side in a Radgrid with checkbox

Hello Dears,

I am facing an issue.

After upgrading from telerik v2009 to telerk v2012 , I can't get my selected rows values in a radgrid with checkboxes from code behind

here is the code in the markup

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True"

PageSize="5" Width="100%" OnPageIndexChanged="RadGrid1_PageIndexChanged"

GridLines="None" Skin="Vista" AllowMultiRowSelection="True" >

<MasterTableView >

<Columns>

<telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" ></telerik:GridClientSelectColumn>

</Columns>

<RowIndicatorColumn>

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<PagerStyle Mode="NextPrev" />

</MasterTableView>

<HeaderStyle Font-Bold="True" Font-Italic="False" Font-Overline="False"

Font-Strikeout="False" Font-Underline="False" Wrap="True" />

<ClientSettings EnableRowHoverStyle="true" >

<Selecting AllowRowSelect="True" UseClientSelectColumnOnly = "true" />

</ClientSettings>

</telerik:RadGrid>

and now the code behind

 protected void  Ok_Click(object sender, System.EventArgs e)

        {

foreach (GridDataItem item in RadGrid1.SelectedItems)

{

CheckBox chk = (CheckBox)item["ClientSelectColumn"].Controls[0];

id = item["ID"].Text; // get the id with its column name

name = item["NAME"].Text; // get the name with its column name

chec = chk.Checked;

}

}

It doesn't even enter in the loop.
What can I do to resolve it ?

Thank in advance for your assistance
