Read only columns when you don't want them to be

hi,
I have a column in my SELECT statement for the grid that I want to use as a checkbox. For example, it reads: 0 as selected. This is automatically set to read only, so I ticked it off in property builder. But when i tick it on in the grid and move off it says that the column is read only. Any way to fix this?

thanks.

LoadLayout throws error Collection was modified; enumeration operation may not execute

The LoadLayout method of the RadGridView will sometimes throw an error "Collection was modified; enumeration operation may not execute." We have found that this happens after the following sequence of events:

1. Define one or more filters in the grid.
2. Use SaveLayout to save the layout definition, which includes the filters.
3. Use LoadLayout to load the layout that includes filters.
2. Use LoadLayout to load a different layout that includes no filters.

Apparently some internal code is iterating through the filter descriptors and attempting to delete them within the iteration. The workaround that we found is to first execute a .Columns.Clear() to remove all of the existing columns. Since they are all going to be replaced by the new layout this produces the same end result, minus the error.

We believe that this problem was introduced sometime between 2010Q1 and 2011Q1. Upgrading from 2010Q1 to 2011Q1 has been one of the most frustrating and time consuming version changes that I have ever experienced. There are a lot of new features and a lot of fixes, but it seems that little thought was given to backward compatibility.

Winform Property Grid Control

Hi,
Do you have a control similar to Winform Property Grid control with property grid features like Number/DateTime masking, list box, categories sorting etc. Winform Property Grid control is neither enough nor flexible enough for customizations.

Thanks,

DropDownList with Textediting and selection

I have been browsing the forums searching for a solution to a DropDownList problem. Our users want to be able to type into the drop down list editor and have the drop down list suggest matches in the list or accept whatever text is typed into the editor portion of the control. We are using a DropDownList with DropDownStyle = DropDown and AutoComplete = Suggest

Currently, when users type in a series of characters in the editor portion of the control which does not match any item in the list, the control refuses to give up focus so users cannot press the "Save" button.

For example, if the list consists of the following items:

ABC123
ABCXYZ
ABQRSTU
A12345

when the user types "A", the control suggests all four choices. When the users types "AB", the control suggests the first three choices. If the user continues typing "ABCD" the control has no suggestions. At this point, the control will refuse to give up focus so the user can press the "Save" button to save the text entered, namely "ABCD".

in short, we want the drop down list to be both a drop down list and a text box.

Any suggestions would be appreciated! Thank you "in advance" for your expertise.

Latest build broke the combobox in the grid?

We put the latest build (Q3) on a few weeks ago. Now all of our comboboxes in the grids stopped working. I did not put on the Q2 version back on to confirm, but I (and my other team members) thought they worked in Q2.

Here is what happens:

1) User drops down a combobox in the grid.
2) User selects an entry from the combobox.
3) THE COMBO BOX DOES NOT CLOSE

Can anyone confirm this? Will there be a fix to this soon? Or do I have to write code in every one of our forms to manually close the combobox? If I have to write code, anyone know what that code would look like?

Thanks for any tips!

Problem with RadDropDownListEditor in 2010 Q3. This problem doesn`t exist in 2010 Q2 SP2.

Hi

I have column GridViewTextBoxColumn.
For some rows I use RadDropDownListEditor in this column. I have random issue that sometimes drop down list cannot be collapsed by mouse click I have to press enter to collapse drop down list. It works fine in Q2 SP2.

Very bad surprise...

Is there any workaround for this issue in Q3?

Visibility of an expression results row when the group header row is collapsed

Hello,

Suppose we have a gridview where I grouped data by a column "Date".
Suppose I add an aggregation expression like "Sum" for one or more column.

When the gridview is totally expanded I see first the Group Header Row that show the value of the group.
Under this row I have the result of the sum for each column of the grid.

The problem is when I collapse the Group Header Row, the row that contains the sum result for each column is hide (with the data).

Is there a way to mantain visible the aggregates results row when I collapse the Group Header Row?

I send you as attachments tow picture:
the first image show in the red circle the row I'd like to be visible after the collapse (second image).

thanks for any answer,
Alcide
