Hi!

 

VERSION: 2010 Q2 SP2

This is my simple application:

 

EditableCheckBoxCellElement:

 

  

EditableCheckBoxColumn:

 

 

CellValue:

Form1:

 

 

 

 

When I run application I see form from attachment viewAfterStartup.JPG. “Standard column” is pinned at left.

 

FIRST PROBLEM

 

If I resize window to smaller size then I have scroll bar on the bottom.

When I start scrolling to right I have problem with text box from custom cells – it overlaps on “Standard column”. This is weird because this problem is only for text box, for check box it is ok (check box does not overlap pinned column) – please check attachments “scrollingCheckBox-OK.JPG” and “scrollingTextBox-NOTok.JPG”. What is wrong in my source code?

 

SECOND PROBLEM

 

When I unpin “Standard column” I see in this column cells of class EditableCheckBoxCellElement. How it is possible? Name of column is correct but cells change type. Check attachment “unpinnedFirstColumn.JPG”.

 

Regards

Hi there,

Just a quick question for you all:  How can I get access to the SystemRows or the header row/cells of a child collection that's empty?  Generally if I wanted to access those guys for a row that already exists I'd go

((GridViewDataRowInfo)row).ViewInfo.SystemRows

or

((GridViewDataRowInfo)row).ViewInfo.TableHeaderRow

respectively, but I can't figure out how to get access to those guys for an empty child collection because there's no "row" object I can latch onto if the parent's ChildRows is empty.  I know they exist somewhere though because they're sitting there on my screen.  I just feel like I must be missing something simple.

For reference, I'd like to set the child NewRow as the currently selected row when a new hierarchy row is created (so insertion would drill through the hierarchy, following the way my users would prefer to enter data) and I need to force an InvalidateRow on a child HeaderRow so that it fires the ViewCellFormatting event when the value of a certain cell is changed (so I can set the header text of the child view even if there are no children yet).

As an aside, in an attempt to solve the second issue I've tried to fire the grid.TableElement.Update() method with a parameter of GridUINotifyAction.Reset and GridUINotifyAction.DataChanged in my grid_CellValueChanged event, and it's throwing exceptions up to my Main method (bypassing my try/catch around the actual Update() call).  Not sure if that's intentional/expected.

Thanks for any direction!

Hey, not sure if I am missing something here, but I am not finding any way to add a new value to the underlying data source when user types a value into the drop down list that does not currently exist. 

I mean, I have my own code that will handle this, I am jsut trying to determine the best time to do what is needed - if the user types in a value that does not exist in data bound list would it make sense to have the code in the TextChanges event, in the Validating event, or somewhere else?

Thanks!

Afternoon,

I've just got a strange behaviour from my gridviews. I recently updated my dataset and went about rebinding everything.

Since then however I have noticed that the alternating row colour no longer works. I am using the default colours.

The property window was telling me that it was set to true so I set this back to false and then to true again incase it had lost its setting but this changed nothing.

I have also set it to false/true inside both the property builder and set programmatically with the same result. I have also tried reopening the project.

Little bit stumped on this one, any one got any ideas?

Kind regards,

Guy

Hi,

I have a hierarchical grid and on the child grids (if there are more than one) on the same level, I'll get some nice captions as Tabs. Now I want these Tabs/Captions also for childgrids where only one grid at a specified level is and also for the MasterGridViewTemplate.

I'm setting already the captions, how can I show them?

Thanks,
Michael

Morning,

I think this question is not directly Telerik related but hopefully someone can help.

I have a datepicker and gridview databound. When I select a row on the gridview, the datepicker updates as I would expect but if I select a row with a blank date (DBNull I believe?) then it still retains the avlue from the previously picked date but still treats it as a null value.

I have looked through all the options I can think of in Formatting and Advanced Binding but nothing seems to work. I have also looked at ways of refreshing the databinding on row change but got no where (plus I don't think that's really the correct way of doing things).

If anyone could help or point me in the right direction i'd really appreciate it!

Kind regards,


Guy

Hi All,
I have a project developed in .NET 3.5 framework using Rad Controles Winfoms Q1. I want to confirm that project developed using Rad Controls Winforms Q1 is compatable with Rad Controls winforms Q2 2010 with out any chane in code. 

Thanks

I have multiple grids with 100,000+ rows in them. I found that allowing RadViewGrid control to do the sorting is very slow and freezes the application while sorting. I am thinking about implementing a SortableBindingList and do my sorting outside the grid and force it to show the newly sorted BindingList when done.

However, this means I have to turn sorting off in the grid, loosing the sort indicator and the context menu options for sorting.

What would you suggest in this scenario?

Thanks,

Hi all,

I am experimenting some troubles in speeding up the filling of a RadGridView. If I fill it row by row (Add method) the result is correct but slow (more than 10s for 300 rows). If I create a GridViewRowInfo array and then fill the Grid with AddRange the task is completed istantaneously, but then the result differs from the one obtained through the Add method (problems in row selection and column resize, not depending on the AllowX properties). In particular I think the my errors are in creating each GridViewRowInfo, that needs a GridViewInfo that needs a GridViewTemplate. Here the code:


Hope someone could help!
Thanks in advance!

I often use image with Telerik controls such MenuItem, buttons, ect. via the Image property or BackgroundImage property.

Do I need to dispose of these images myself?

Thanks,
