I was looking around in the forum to find something about the thumbnail quality and all i got was april's old posts speaking about a fix and OctreeQuantitizer

With the last version of ajax controls there is a way to fix the thumb quality?

Or a fix in c#

Thanks for the attention

Drag and Drop

Can anyone tell me more about the drag and drop feature with the grid? I have a simple grid that i want to be able to reorder the items, and once the items are in correct order i can use a button to loop through and retrieve that order. So far i can only select on a row but when i move the row it goes back to it's original order.

Thanks

2 radGrid on one aspx page

I have a page that when I first load the page, I want to show a grid that has student information on it. When the user selects Teacher from the dropdown box, I want the student grid to disappear and the Teacher grid that has totally different information and headers to appear.

I also want to enable paging on this page.
My problem is the "NeedDataSource" for both grids. It doesnt work for the teacher.

how to disable radtooltip?

i've got a checkbox that i want to be able to control whether or not the tooltipmanager i have shows the tooltip. i'm using a raddatagrid and the tooltips work fine on it, but i want to be able to control whether or not it shows.

so i put an asp checkbox control and on the checkchanged event, i set the mytootipmanager.visible = mycheckbox.checked. this makes it invisible, but then won't re-enable it. ie, once it's off, it's off.

ideas?

[Solved] filtering options for system.string column

I am wondering why the following options are showing up in the FilterMenu for a column that I have defined as a system.string:

GreaterThan
LessThan
GreaterThanOrEqualTo
LessThanOrEqualTo

I don't understand why numeric filters are showing up on a column defined as a string. Here is how the column is set up:

<telerik:GridBoundColumn DataField="request" HeaderText="Request" SortExpression="request" DataType="System.String" UniqueName="request" FilterListOptions="VaryByDataType"></telerik:GridBoundColumn>

Rad Grid Drag and Drop - Check if Valid

I found the examples of drag and drop for a Rad Grid. However, I would like to check if it is valid to do the drag and drop. Because of server side specific data relationships, I would like to check client-side whether it is valid to do the drag and drop from on place in the grid to another. Do you have any example of such a check?

Thanks in advance,

K.E.

Many-To-Many Mappings in a single cell

What is the best way to handle a many-to-many mapping in the DB for a table that is being represented with the Grid control using databinding?

Let's say I have a employee contact table and it currently has a FK for ContactTypeID which is a lookup to one of a variety of contact types.

Currently it is a databound dropdown list in the grid. But let's say that I want to make it a many to many mapping by inserting a mapping table called EmployeeContacts which contains a FK to Employee table and a FK to ContactTypes table.

I still want a single grid that shows and edits employee contacts from the Employee table, but I now want the column that used to be a simple drop down of Contact Types to be a drop down with multiple check boxes or some other kind of column that lets me choose more than one selection. Then I want to keep as much of the databinding as possible, or do I have to manually code the back end hook up of the checking and recording of the checkboxes upon edit form submission?

Anybody have an example of this kind of usage with RadGrid? m2m mapping tables are a pretty common need.

Thanks in advance,
Rob

[Solved] Set different inactive window styles

Hi

I have created a custom css for the RadWindow and have customized the inactive window display through it.

There is now a requirement to have different inactive window styles based on the context in which a rad window is popped up.

I would like to know if this is possible through javascript or if there is a way to change the css to support different styles.
