Add OnClick handler to anchor tag in document manager

How do I add a onclick handler to my DocumentManager control? I can alter the href or URL property from a ExtendedFileProvider to add "javascript:clickHandler()". But this isn't good practice.

I have both a LinkManager and a DocumentManager. How do I add an onClick to the <a> tags that get generated by these controls?

Thank you!

Drop Down List error in FormTemplate

I am getting an error:
'ddlWebPages' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value

This happens only when I click the Add New Record button on the grid. the ddlWebPages has no issues when I am in edit mode.
I believe this has to do the the snippet SelectedValue='<%# Bind("security_webpage_id") %> of the dropdownlist.
I searched for solutions but none of them worked. There was one suggestion for SelectedValue='<%# Eval("security_webpage_id") == null ? null : Eval("security_webpage_id") %>'. That didnt work for me. Has anyone dealt with this issue? HELP! I am so close to finishing my grid.

Dynamically created textbox in RadGrid

Hello,
I'm have a RadGrid with 2 template columns. During ItemDataBound I'm dynamically creating a textbox and adding it to the Grid like this:

GridDataItem gdi = (GridDataItem)e.item

TextBox tb = new TextBox();
tb.ID = tbID;
tb.EnabeViewState = true;
gdi["column name"].controls.add(tb);

"Colum name" is a template column in the grid

I have another template column with a button in it that is created at design time. When I click that button I want to be able to find the dynamically created text box in the same row of the grid and read it's value.
How do I accomplish this?

Thanks in advance

Large performance hit on e.Item.Expanded = true

In the ItemCommand event on my RadGrid I have the following section:
if (e.CommandName == RadGrid.ExpandCollapseCommandName || e.CommandName.Equals("RowClick",StringComparison.InvariantCultureIgnoreCase)) {
e.Item.Expanded = true;
e.Item.Selected = true;
}

The e.Item.Expanded being set to true is taking 10-14 seconds to resolve, what could be happening that would cause such a large performance hit?

Get current Url from radwindow

Hello, I am struggling getting the current url for the radwindow. I always seem to obtain the original url.

I have a radwindow hosting a webpage where I am able to perform searches internally, Just as google, yahoo etc, the url is populated with a string of information identifying the performed search. I need to pull the new url from the radwindow and pass it to a model popup I am using to save the string.

I have tried several options but none seem to get anything but the original url.
radwindow.get_NavigateUrl()
radwindow.Geturl() - doesn't work at all.
document.getElementById("radwindow").src

Please help,
thanks.

Grid Filtered by Combo with Checkboxes in Filter Templates

Hi all,

Using VS2013 with UI for ASP.NET AJAX Q3 2014 SP1. Below RadGrid Demo is my Prototype, 1st Grid (i.e. referencing to RadGrid1).

http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx

I would like to have the flexibility to Filter the Grid with Check all, Single Selection or Multiple Selections from Filter Templates via Checkbox. Existing Functionality of the Above Grid Should remain the same.

Is it possible to Filter above Grid with ComboBox - Selection with Checkbox like below link?

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/checkboxes/defaultcs.aspx

Thanks a lot
