EditItemTemplate + IBindableTemplate + ExtractValues OnUpdateCommand = "Editor cannot be initialized for column: <columnName>"

Hello.
I am creating a servercontrol that inherits the radgrid.
I am creating it on "OnLoad"
I want to create a GridDropDownColumn that will be filled by a DataSet.
From what i read i saw i have 3 options :
1) GridDropDownColumn with DataSourceID ,
2) DropDownColumn that can "bind" to the gridDataSource ( the gridatasource must have both id and text - and i can only have the id)
3) Template.
I can't use number 1 and 2. so the only option is template.
I created a class for ItemTemplate, and one for EditItemTemplate.
The problem i have is with the EditItemTemplate

class DropDownListTemplate : IBindableTemplate<br>

{<br>

string dataField = null;<br>

bool enabled;<br>

DropDownList ddl = null;<br>

<br>

public DropDownListTemplate(string dataField, bool enabled)<br>

{<br>

this.dataField = dataField;<br>

this.enabled = enabled;<br>

}<br>

<br>

void ITemplate.InstantiateIn(Control container)<br>

{<br>

ddl = new DropDownList();<br>

ddl.Enabled = enabled;<br>

ddl.DataBinding += ddl_DataBinding;<br>

container.Controls.Add(ddl);<br>

}<br>

<br>

void ddl_DataBinding(object sender, EventArgs e)<br>

{<br>

ddl = (DropDownList)sender;<br>

ddl.ID = dataField;<br>

GridEditFormItem bidingContainer = ddl.NamingContainer as GridEditFormItem;<br>

string value = ((DataRowView)bidingContainer.DataItem)[dataField].ToString();<br>

<br>

ddl.Items.Add(value);<br>

<br>

}<br>

<br>

IOrderedDictionary IBindableTemplate.ExtractValues(Control container)<br>

{<br>

OrderedDictionary dick = new OrderedDictionary();<br>

dick.Add(dataField, ddl.SelectedValue.ToString());<br>

return dick;<br>

}<br>

}

I wanted to make it only ITemplate but i got an error saying i need to make it IBindableTemplate.

On ItemDataBound i find the template, get the dropdownlist and bind it to my DataSet.
When i push the "Edit" command it works. The problem appears when i push "Update".

On the "GridTelerik_UpdateCommand" event i need to Extract the new values.
But i get an error at : ((GridEditableItem)e.Item).ExtractValues(newValues);

The error is : "Editor cannot be initialized for column : <columnName> - where columnName is the uniqueName of the TemplateColumn.

Is there a way i can resolve it. Does it have a problem because i instantiate the column editItemTemplate on Load? In case there is a better solution for this situation please advice me.
Thanks.

RadAjaxManager Making RadNumericTextBox Value Disappear

The server I'm developing on is running IIS 7.5, and my company uses Internet Explorer 8. In my program, I have a series of steps that a user has to go through in sequence. As one step is completed (via a button click), another step loads. The steps are each in Panels, and I use a RadAjaxManager to update the next panel on button clicks so that the next panel is made visible. The odd problem that I'm having right now is that whenever the next panel loads, the first RadNumericTextBox within the newly loaded panel will not hold the value typed into it. For example, if, once the text box loads, the user types "100" and goes to the next text box, "100" will stay in the box, but if I were to try to find its value server-side, it would be blank. If i were to click on the text box again, the value "100" will disappear. Upon typing in the value again, it will change to "100.00" like it's supposed to whenever it loses focus, and the value will be available server-side. This happens randomly, but if it does happen, it will only happen on the first time and on the first box. Any help is much appreciated.

Here is my Markup:

Assigning text box value while sorting grid

Hi,
I am using telerilk rad grid to show details of employee name and ID with pagination. I also have a text box for employee name which should populate first employee name in the grid page. When i change the grid to second page, the text box should show the first name of second page. I am assigning the text box value in the ItemDataBound event. The value is assigned to the text box but it is not showing in the UI since the grid paging is done in AJAX and the page is not rendered. How to get the text box populate without rendering the whole page.
Thanks,
S, Karthi

Filter image Width???

Hello,

I have a Rad Grid and on it I have 2 filters.. The boss told me he wanted to use a button/image of [Search] and not the default icon that is used for Filtering... I figured out how to change the Icon to use an image via the code below:

.rgFilter
{
background:url('../images/search.gif') !important;
}

But when viewed in a browser it clips the image to the same size of the old Icon...

where to set this size/width??

Set and get Button ID in RADGrid VB.Net

Hello

I need to set the ID of a repeated button in a RADGrid and then get that ID in the VB code on the server side when it is clicked.

Hers what I’m looking to do...

1) Using a RADGrid I want a Button in one of the columns (Got it/Can do)

2) When that button is clicked it calls a set of code (function/sub) server side VB

- I want to give each button a defend ID using the record ID in dataset the data set that’s building out the table for the grid.

- The code that is called will be the same no matter what button in the list is clicked

- The code it calls can know/get what button ID was clicked so that it may use the ID to drill in to the DB.
(I know how to do the DB work, just need the Button ID that was clicked, sever side VB)

-Problems/help??

- I can’t see how to set the ID via the RADGrid designer

-- I do see how to for "tool tip" and the like but not the button ID (not the button text)

- Where do I set it to call a sub or function that I have in the VB code page?
- What code would go in go in the Sub:

Sub GridButtonEdit()

BtnClkd = Get.GridButtonEdit.ID
End Sub
--- Something like that???? ---

If it’s not possible to set the Button ID (as I see it’s some random long string now) then is there something I could set that I could then get in the code that it calls?

Thanks for the help!

Can You Databind a Field to a Chart Series ToolTip?

Greetings,
Can the ActiveRegionToolTip of a RadChart be databound to a value returned directly from a datasource? I am able to set it to the X or Y value in the Chart datapoint using #Y, etc., but if the query is returning extra text in a different field, is there a way to directly feed that into the ActiveRegionToolTip? (i.e., without resorting to server side code when the items are databound).

Thanks
Dave
