Unable to save when Updating / Inserting in Grid

I have had to make changes to my FormTemplate fields to keep it from getting an error.
I believe it is because I have changed the fields from using selectedvalue and checked
set to a BIND to using Eval expressions. After making these changes when in edit mode
any changes put into the template fields don't seem to be populating the GridEditableItem
which I believe is the reason for the saves not going to the database now. If I remove
everything under the EditSettings then the grid goes back to successfully saving the
changes to the database. Below is both my markup and code behind. I can't hitting roadblock
after roadblock. Any help would be much appreciated?

Markup code:

RadGrid Batch Mode Get Value from Popup or bind another dropdown.

I am trying to get a value from a popup window.

My process goes like this.

When a user clicks on a value from a RadDropDownList (CUST_NBRDropDown) I have OnClientItemSelected fire a popup

<telerik:RadDropDownList ID="CUST_NBRDropDown" runat="server" DataSourceID="Customer_DDL" DataTextField="account_name" DataValueField="account_number" DropDownHeight="400px" SelectedValue='<%# Bind("CUST_NBR")%>' OnClientItemSelected="OnClientItemSelected">

</telerik:RadDropDownList>

function OnClientItemSelected(sender, eventArgs) {

var item = eventArgs.get_item();

//alert("You selected " + item.get_text() + " with value " + item.get_value());

retVal = window.open("BSDM_PLANT_BACKNUMBERS_popup.aspx?acct_num=" + item.get_value(), "Popup", "width=300,height=100");

retVal.focus();

}

On the BSDM_PLANT_BACKNUMBERS_popup.aspx page i have a RadComboBox that i want the user to be able to select one of the values from.(This dropdown is populated from a Oracle DB. with the filter from the original 'CUST_NBRDropDown' dropdown.)

After they select a value i want to return the selected value back to the BSDM_PLANT_BACKNUMBERS (Parent) page to a Textbox in the same row as the original RadDropDownList.

<asp:TextBox ID="CUST_NBR_txt" runat="server" Text='<%# Bind("CUST_NBR") %>' Visible="true"></asp:TextBox>

So far I have not been able todo that.

If possible instead of doing a popup i would like to be able to have the dropdown that is populated in the Popup window to be in the radgrid row. but from my understanding i cannot bind the dropdown in "batch edit mode" after the CUST_NBRDropDown is selected since this is all client side functions...

Any help would be greatly appreciated!

Keyboard issue with radtoobar/radmenu

We have requirements for 508 and WCAG within our system. I have been testing the ability to move between the controls using the keyboard and ran across a problem with the radtoolbar so am looking for a way to get it working.

In the example below i can use the keyboard and tab through the open, save, cancel options on the main tool bar. When i stop on the "open tab" option i use the down arrow key to open up the radmenu. i can use the up/down arrow to move up down through the menu without any issues.

the problem comes in when i need to expand the "level 1a" menu. when focus is on that item, i hit the right arrow to expand the menu out. however, what happens when i click the right arrow key is that the focus moves to the "save" menu option on the toolbar. so i can't open that lower level menu and continue using the keyboard to get into the level 2a-e menu options.

Is this a bug in the controls? Is there a way to workaround the issue so i can use the keyboard to access the level 2 menu items?

RadWizard Next button when clicked IsPostBack = False

I have a standard RadWizard. It is within an RadUpdatePanel. On page load I have a chunk of code.... Product is a global Object

If Not IsPostBack Then

'do something

* Session("Product") = Product

Else

'do something else

* If Not isNothing(Session("Product")) Then

Product = Session("Product")

End If

End



* = Breakpoint

I have placed a breakpoint within 'do something' and one within 'do something else'.

When I run the page the 'do something' code runs as expected. The 'do something else' is not run - as it's not a postback this is correct.

Whenever I click the Next button of the RadWizard the 'do something' code runs - hovering over IsPostback shows that it's value is FALSE... but it should surely be TRUE. If I continue from this breakpoint the 'do something else' code runs - hovering over IsPostback now shows it's value to be TRUE.

Why are both the Not IsPostback and the IsPostback code executed when the Next button is fired?

RadScheduler MonthView rsAptResize is not being rendered

hi all,
I am using RadScheduler in monthview. I made the appointment editable, clickable on clientside ( using clientside event, I am familiar with those).... But I am not able to make the appointment Resizable, Moveable.
( it is Resizable and Moveable in TimelineView).

I examine the HTML that being rendered, I notice that the Appoinments HTML does not have the DIV rsAptResize as it does in Timelineview. (refer to the attachment)

What could possibly caused this ? Can someone shed a light. May be someone from Telerik is familiar with the way the control is being rendered...
( I customize the RadScheduler and Appointment template, can this be a reason why? But it work find in TimeLine view? And in MonthView, I apply the same process. In MonthView the Appointments are clickable but note moveable...)

regards.

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
