This one is a little bizarre, so forgive me if I don't describe this perfectly.

I'm in the process of updating custom web parts from our 2007 to 2010 deployment. For 2007, I had a Smartpart-style web part (ascx control wrapped in a web part class). For 2010, I'm taking advantage of the VS2010 Web Part projects (Visual Web Part in this case) and the native SP debugging.

The control for the webpart is designed around the following structure:

RadAjaxPanel
    RadTabStrip (2 tabs)
        RadMultiPage
            Pageview1
                 Formview (bound to ObjectDataSource)
            Pageview2
                 RadEditor

Due to databinding and speed concerns, the original web part was designed to use the RenderSelectedPageOnly option on the multipage. So with this setup, I'm experiencing the following behaviors:

1. When RenderSelectedPageOnly=false and the formview is in the display view, everything works great - editor loads content properly, allows editing correctly, etc.
2. RenderSelectedPage= false, Formview in Edit view - when you click on the tab to bring up the Editor, there is an outline around where the editor should be, but there is no content nor any controls.
3. When RenderSelectedPageOnly = true, the Editor does not display correctly, regardless of what mode the Formview is in.

Occasionally, with #2 and 3, the following javascript error displays momentarily:

Sys.ArgumentUndefinedException: Value cannot be undefined. Parameter name: type from ScriptResource.axd.

Any thoughts on what could be causing this strange series of behaviors?


ETA - I spent more time playing with this, and the problem seems to be with the Ajax controls (or at least how the editor is working with them). When I remove the AjaxPanel and just let the webpart go pure postback, everything works great. I then tried it with a RadAjaxManager instead of the panel, and the same behavior was displayed as with the panel. Wanted to include that info if that helps track this issue down.

Text area in Radgrid.

I like to put an text area in radrgid as GridBoundColumn.

 

Have multiple rows and a long width.

How I do that?

I found the following code below, but somehow even it nevers shows it in Edit or Insert mode to the code never got triggered. Please help.

 

protected void rgTask_ItemDataBound(object sender, GridItemEventArgs e)

 

{

 

// in insert mode

 

 

 

 

 

 

if ((e.Item is GridEditFormInsertItem) && (e.Item.OwnerTableView.IsItemInserted))

 

{

 

GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;

 

 

TextBox txtbx = (TextBox)insertItem["Task_Detail"].Controls[0];

 

txtbx.MaxLength = 500;

txtbx.Width = 800;

txtbx.TextMode=

TextBoxMode.MultiLine;

 

 

}

 

//in edit mode

 

 

 

 

 

 

if ((e.Item is GridEditFormItem) && (e.Item.IsInEditMode))

 

{

 

GridEditFormItem editItem = (GridEditFormItem)e.Item;

 

 

TextBox txtbx = (TextBox)editItem["Task_Detail"].Controls[0];

 

txtbx.MaxLength = 500;

txtbx.Width = 800;

txtbx.TextMode =

TextBoxMode.MultiLine;

 

 

}

 

 

}

Thanks!

Hi,

I want to dynamically add/Remove  GridButtonColumn in a RadGrid. In a regular ASP.Net Grid I achieved this by setting  Grid1.AutoGenerateSelectButton = false OR Spreadsheet.AutoGenerateSelectButton = True;

I want to let the users select rows in a Grid only on certain occasions. How can I show / hide Select column in RadGrid? Can someone provide me  clues?

Thanks,
Prava

I have a data bound Hierarchal multi-level TreeView.  Why doesn't it display in the order of the data that it is bound to?

The data comes from a database and I select and order the data as part of the data source.

Any Ideas?

Hi,

I've found several examples of how to bind GridDropDownColumns to SQLDataSources and such, but not how to bind such column to an ordinary List or DataTable.
I know that I can use a GridTemplateColumn containing a dropdown-control and populate the control in the event handler of ItemDataBound, but a more direct approach where the column is bound to something in the grid's datasource would be a lot nicer.
Is this possible?

Thanks!

I am trying to use a RegularExpressionValidator on a RadMaskedTextBox that is collecting a US Zip Code. I am using the following properties:

Mask="#####-#####"
DisplayMask="#########"
DisplayPromptChar=""
SelectionOnFocus="CaretToBeginning"
ResetCaretOnFocus="true"

My RegularExpression is ^((\d{5}(-|\s)\d{4})|(\d{5})$

This fails for 32608 but works for 32608-0000 when using RadMaskedTextBox

The regular expression works when I do not use a RadMaskedTextBox and fails when I do. I read that the RadInput validates against a stripped version of the Text which should validate both 32608 and 32608-0000.

Hi 
i have database update problems with two related listboxes , the errors appear when i try to move an item from the first listbox to the second (it seems like the fields value is not transferred with the item) or when i try to delete an item from the second listbox (scalar variable isn't declared error)!
Got a problem also with my ajaxpanel it dosent seem to work (the page reloads when i try to move an item)

i would liked to attach my project but it says File is not of correct type so here is the aspxpage code !

I see this issue in IE and not Firefox.
When I click on the export to excel button and click open (instead of Save), the excel file has a weird name 56%67%79%......xls

When I hit save it picks up the right name that i mentioned.

            MyGrid.ExportSettings.FileName = HttpUtility.UrlEncode("MyFileName", System.Text.Encoding.UTF8);

Any suggestions how to fix this. I am using 2009 Q2.

Thanks,

hi
I come across some problem with the exporting. The issue is that I can't export all the record in the grid even I set "IgnorePaging"  to true; it only save the current page. The RadGrid is on a updatepanel, and the event for imagebutton click as follows

 

protected void ImgbtExcel_Click(object sender, ImageClickEventArgs e)

{

RadGridEmp.ExportSettings.ExportOnlyData =

true; 

 

 

RadGridEmp.ExportSettings.IgnorePaging =

true;

 

 

RadGridEmp.ExportSettings.OpenInNewWindow =

true;  

 

 

RadGridEmp.MasterTableView.ExportToExcel();

}

everytime it only save the current page.
