Hello,

What I'm trying to do is essentially create a "Read-Only" combobox so the user can't make it dropdown or otherwise select anything.  I've prevented the dropdown, but they can still change it the value if they select it and then use the arrow keys to scroll down.  Is there a way to prevent this?

I have a RadUpload control in EditTemplate inside a RadGrid.
I add the client code to add addtional field with TextArea type allowing user to enter comment for the uploading file.
And that additional comment field is a required field, also only 500 characters max limited.
I want a TextArea type because I want to user to see all the text they enter and input type=text just won't do the justification.
I seem to have a problem to get the addional field's value at client side code. 

I use  
   var radGrid = $find('<%= rgGrid.ClientID %>');

to get the grid control
and  
   var radUpload = $telerik.findControl(radGrid.get_element(), "rdProfile");
to get the upload control

When I try to retrive the value of the additional field by code similar to
   var descValue = $get(radUpload.getID() + 'Title' + i).value 
I am getting javascript error saying "object needed"

Anyone can help?
I attached my code

Hi,

I have two DataTable objects that both contain the same data (first contains data before a certain change, second has the data after that change).

Assuming that both tables have the same number of records, is there any way to show differences between the tables in a nice, user-friendly way using Telerik RadGrid (or maybe any other Telerik control)?

Thanks,
Michael

I have a simple FormTemplate that I am trying to grab the values from to perform an insert/update. I am trying to grab a Listbox to create a comma delimited list of the values that it contains. When I try to access it I get a null pointer. However, I can successfully access other controls in the same FormTemplate. Anyone have any ideas?

The control I am trying to access is the lstSelectedUsers control.

Hi,

I'm adding a RadGrid to a page and am having issues getting my table data to display.

The grid is generally working, but every cell displays as 'system.data.datarowview' - looks like it's calling ToString() on the wrong object?

I am populating the grid entirely in code, but am declaring it statically in my ASPX.
I create the columns in the Page_Load method (when !IsPostback) - there is a variety of GridBoundColumns and GridHyperlinkColumns. The columns are instantiated, added to the grid.MasterTableView.Columns collection, and *then* have additional properties set.

When the time comes to populate the grid (during a partial postback event), I have a helper class that produces a DataTable object with columns with names that match the GridColumns in the grid.

I finally call Rebind() and set the DataSource of the grid to my DataTable in the NeedDataSource event.

When stepping through some of the events (I create a custom paging control), I can clearly see that my data is present in the DataSource, but it's not making it through to the grid.

If I set the grid to AutoGenerateColumns=true in my ASPX, I get duplicate columns, but the auto generated ones are displaying my cell data correctly.

I suspect I'm missing some step in wiring the DataTable columns to the GridColumns. Any advice?

Thanks,
Stefan

hi,

i used the textbox inside the panelbar i used the following codes the find the controle but the value i'm getting from the textbox is null

foreach (RadPanelItem PanelItem in RadPanelBar1.GetAllItems())
{
RadTextBox txtAge = RadPanelBar1.FindControl("txtAge") as RadTextBox;
RadTextBox txtWeight = RadPanelBar1.FindControl("txtWeight") as RadTextBox;
health.Age = Convert.ToInt32(txtAge.Text);
health.weight = Convert.ToInt32(txtWeight.Text);
}

the value of txtAge and txtWeight is always null even if i gave different value in runtime

I have 'program' radlistbox that I am populating dynamically. I also add a RadListBoxItem '[ ALL ]' to this listbox which is used to select all the items.

I populate the other radlistbox depending on the selection in the 'program' radlistbox.

The issue is: I selected '[ ALL ]' from 'program' listbox. This selected all the items in the listbox and populated the other listbox accordingly. But now when i select just one item from the 'program' listbox nothing happens, the 'SelectedIndexChanged' does not fire.
Please help???

-- Code to insert the RadListBoxItem

Me

 

.rlbProgram.Items.Insert(0, New RadListBoxItem("[ ALL ]", 0))

-- Code that I use to loop through the listbox to select them all when '[ ALL ]' is clicked.

 

Select

 

Case Me.rlbProgram.SelectedIndex

 

 

Case 0

 

 

For i As Integer = 1 To Me.rlbProgram.Items.Count - 1

 

 

Me.rlbProgram.Items(i).Selected = True

 

 

 

 

sPrograms.AppendFormat(

"<Program id='{0}'/>{1}", Me.rlbProgram.Items(i).Value, vbCrLf)

 

 

Next

 

 

 

 

 

End Select

 

I just upgraded to the new Q2 2010 tools and the RadGrid's AutoGenerateHierarchy is gone!  Now all of my DataRelations that I set up in the datasets do not have any impact on the RadGrid and I only see the top level.  Has the functionality been removed or just moved to a different method?  How can I get this to work in the Q2 tools?

I've noticed that with you set EnableAutomaticLoadOnDemand="true" and Filter="StartsWith", when you select one of the items and then start scrolling it starts filtering out all the other items and the message box shows incorrect counts and allows you to continue scrolling until you reach the count it mentions.

It's kind of hard to explain, but you can see it being done on your demo page:

http://demos.telerik.com/aspnet-ajax/combobox/examples/loadondemand/automaticloadondemand/defaultcs.aspx

If you open the drop-down, select one of the options and then open up the drop-down you'll see the issue I'm referring to. It starts clearing out the other items, but still allows you to scroll.

I have to assume this is a bug with the AutomaticLoadOnDemand feature.

 

I ´m not using DatasourceID, and I don´t know why happend this.

This is a common error, some times happend. And I don´t know which is the problem.

Thank´s.
