I know that there are many forum posts regarding filtering but I am having the hardest time trying to figure out how to accomplish this filter scenario:

I have 4 columns, Rdel, RAdd, RMod, RErr.
right now I have those columns set as Integer type in my datatable that I bind to the radgridview.  I handle changhing the values as need be but I need to be able to use filters so that I can not rows.  The way I have been trying to set the filters up I have used a custom context menu that uses a check type menuitem.  So when that value changes I am trying to add or remove descriptors.  So I may have many or no filters applied to the grid.  Right now I have something like this and it sort of works but I just wanted to kbnow if there is a better way of doing this.



If there is a better way to handle this scenario I would appreciate any suggestions.   The main thing is that I will add and remove filters on a single column and not want to lose the existing ones.  I would also need to be able to only see the rows that have a 1 in any of those columns.  A row could have a 1 in conAdded, conModified, and conDeleted.  That is so I can undo a single operation, such as a delete and still know that row was added.

Thanks once again.

But it does not show the data from the list. the grid has 2 columns: Capacity, Count

Does anyone knows How I can Bind Mylist to the grid?

Hi all,

I have a grid view with multiple columns, on which I want to apply filtering. When I use multiple filters, I get an exception of type

ArgumentOutOfRangeException
Index must be within the bounds of the List.
Parameter name: index

I can't find the cause of this, so does anybody have an idea of what's going wrong here? Grouping is also applied to the gridview (but I also tested without grouping with same exception as result).

Hi Team,

When doing some research on radmaskedittextbox(DateFormat)  i observed the following things.

1.By default maskedittextbox is allowing user to select only date between 1st of current month and
current date.

2.it is not allowing back date and also future date.

3.I am not able to clear the default date of radmaskedittextbox(DateFormat)  in runtime.

but in my application i want to allow back date and also future date.please tell me how to achieve this.

My Code snippet:
 private void rcStartDate_SelectionChanged(object sender, EventArgs e)
        {        
            rmebStartDate.Clear();
            rmebStartDate.Text = "";
            rmebEndDate.Value = "";
            
            rmebStartDate.Text = rcStartDate.SelectedDate.ToShortDateString().ToString();
            rcStartDate.Visible = false;
        }


Thanks

Dear Telerik team,
                              I am designing a style for CheckBox control and the problem i face is "I cannot find property to change CheckMark color and backColor of the box for check mark. The property i guess would have worked is "RadCheckBoxElement.ToggleState=Ok.Pressed. But this property produces arrows etc ( for whatever shape i choose from available options)

none of the property changes the dark brown color of check and the box.

Thanks

Hi all,
I've a problem with HTMLFormatProvider and font-style.
I'm using a radRichTextBox with richRibbonBar (but the problem is also present with a button that execute radRichTextBox1.toggleItalic() ). For example, I have write the string "foofoofoo" in italic inside radRichTextBox and then, using HTMLFormatProvider, I've got the text associated to the document. 

This is the ExportToHTML function

public string ExportToHTML(RadDocument document)
        {
            HtmlFormatProvider provider = new HtmlFormatProvider();
            return provider.Export(document);            
        }

This is the string returned:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>Untitled</title><style type="text/css">
.p_4451D050 { margin: 0px 0px 12px 0px;text-align: left;text-indent: 0pt;padding: 0px 0px 0px 0px; } 
.s_C54C634B { font-family: 'Calibri';font-style: System.Collections.Specialized.StringCollection;font-size: 16px;color: #000000; } 
</style></head><body><p class="p_4451D050"><span class="s_C54C634B">foofoofoo</span></p></body></html>

There is a problem in font-style settings of css class, because it doesn't write "italic" but "System.Collections....".
So, when I send a html-email in this format I lost this font setting..

I've tried with XamlFormatProvider and italic (as fontweight) is correct.

Thanks a lot for your help

After searching the forums for some time (days, well 2 days) I finally have a solution on displaying an Error Icon in a cell of a RADGridView i.e. like in SQL Management Studio when a certain criteria is met.
Scenario 1: Validate all cells in a row simultaneously
Scenario 2: Validate an individual cell

So here goes:
Solution 1: Validate all cells in a row simultaneously





AND TADA :                                                                        **** THE MAGIC ***** 


That's it folks. You can use EITHER Solution 1 or 2, but you have to include the magic irrespective of which one you choose.
Hope this saves you some hours.

How do you enable a pivot table with your control?

How can I highlight RadSplitButton to make it more visible  when focused. I tried setting up explicitly IsMouseOver = true on focus enter event, but it doesn't work. Is there any other way I can do it?

Thanks.

There is a property for the main masterviewtemplate of a RadGridView to set the rows to auto size if you have a column's WordWrap turned on (i.e., this.radGridViewRequests.AutoSizeRows = true ).  This works slick.
BUT, for a child template there is no such property to AutoSizeRows if you have a column's WordWrap turned on.  So what is one supposed to do to get the child template rows to resize properly?
