Hello,
I would like to bind the PropertyGrid to a datatable which has only 1 Column.
I want to use the PropertyGrid as a detail form for editing a Datatable with 1 column (like Parameters etc.).

Is this possible or do I have to convert to an object by code.

thanks for an answer.

Folder Hierarchy

Hi,
Can we have folder style hierarchy for many to many relationships?
If not how can I easily align the child view columns to its parent. The gird that I am using have the same column headers for all views. I am using ViewDefinitions and the column headers are quite complex and can have around 6 rows (just headers). Also while expanding the hierarchies (can go to n levels), I get scroll bar hell.

Thanks
Deepak

Recommended Telerik Control

Telerik Forums,

The company I work for has a scenario that I'm sure other people have faced. We have several tables of records that are mainly used as code values, status codes, etc. Each of these tables has an Active flag so that as old values are no longer needed we can flag them so they aren't displayed to the user. However, when looking at an older record it is very possible that you would need to populate a value that is now inactive.

I believe/hope that either the telerik ComboBox or MultiColumnComboBox could assist us with this, I'm envisioning that the ComboBox would load both the active and inactive values and that with a filter applied only the active values would be displayed in the drop down for the user to select on new data entry.

Does this sound like something that can be achieved with a telerik control?

Thanks in advance,

Jeremie

Merge Fields

Hi,

Does the Telerik WinForms RichTextBox support Merge Fields?

I found an example for MailMerge in the Silverlight version of RichTextBox which allows the use of certain Merge Fields. However the functionality does not appear to be in the WinForms version?

If not, is there any plans to add it?

Thanks,

Mark.

Set ForeColor of AutoCompleteSuggest DropDownList

Hi,

I'm having difficulty working out how to set the colour of the items in a non-databound list, when the user types in text to bring up the autocomplete suggest mode.

I've set the colour of the ForeColor property in the items according to a business object that is set to the Value property in each item.

When the user hits the drop down arrow, the list populates with red and black items. However when the user types in 'L' and the list displays, I'm trying to get it to display the same black/red colours but it seems the items in the AutoCompleteSuggest.DropDownList.Items do not have their Value/Tag properties set from the original items.

Can you suggest a work around for this?

My experience with .Net is 7 years. My experience with Rad is about 1 month.

count filtered rows in group

Hi:
Is there a way of counting the visible rows after applying a filter or multiple filter and a group or many group?
eg: There is a group template by Age column and I apply a filter in city column. How can I count the filtered rows?

   Our code as follows:
  radGridView_Filtered(.......)
{
    label1.Text= radGridView.MatserTemplate.ChildRows.Where(o=>o.City='NanJing').Count;
}

If there is only filter ,the label1's text display filtered rows .But if there is a group ,the label1's text display zero.
I want the label1's text display filtered rows .

Look forward to you

from current row to next row by Enter key in group and filter

Hi :
     The radgridview enable group and filter. The user want to skip the next row from current row and the next row into edit mode by Enter.
       1. Our code as follows to achieve the enter key, :
        private voi dg_KeyUp(.....)
        {                  ......
              if((dgCut.CurrentRow.Index+1)<dgCut.Rows.Count)
              {
                     var row =dgCut.Rows[dgCut.CurrentRow.Index+1];
                     dgCut.CurrentRow=row;
                     if(dgCut.CurrentCell!=null)
                     { dgCut.CurrentCell.BeignEdit();}
               }
         }
      but if there is a filter by column 'Name', the enter key event behavior is strange.The current row can not skip to next row.

      To solve the problem with filter,we update the code as follows:
        private voi dg_KeyUp(.....)
        {                  ......
              if((dgCut.MasterView.CurrentRow.Index+1)<dgCut.MasterView.Rows.Count)
              {
                     var row =dgCut.MasterView.Rows[dgCut.MasterView.CurrentRow.Index+1];
                     dgCut.MasterView.CurrentRow=row;
                     if(dgCut.MasterView.ViewTemplate.CurrentColumn!=null)
                     { dgCut.CurrentCell.BeignEdit();}
               }
         }

      the result as we do is :it is Ok by Enter key if there is only exsit filter.It is not Ok if there is group and filter.
     How to achieve the enter key behavior if there is  a group or multiple group and a filter or multiple filter?
