We have multiple RadGrids with the MasterTableView configured thusly:
<MasterTableView EditFormSettings-PopUpSettings-KeepInScreenBounds="true" EditMode="PopUp" TimeZoneID="Central Standard Time">If a record from the database has a null datetime value, the min value of DATETIME data type is used (01/01/0001). When the grid tries convert UTC to CST, we get the error: The added or subtracted value results in an un-representable DateTime.
Parameter name: value.
How can this be handled so the Grid display an empty cell when a null datetime is encountered?

Trying to add a text box and button into a Column Group Header server side and can't seem to get to the cell of the specific header. I know how to set the text and all but want to place controls into the header.
protected void RadGrid1_PreRender(object sender, EventArgs e)
{
foreach (GridColumnGroup cg in RadGrid1.MasterTableView.ColumnGroups)
{
if (cg.Name == "HeaderGroupName")
{
cg.HeaderText = "TEST";
}
}
}

Hello
I'm asking you a question because there's a tricky screen.
The screen consists of Grid and Dialog, as shown below.
[StudentGrid]
[StudentDialog]
Hello,
I'm trying to organize the screen, so I'd like your help.
If I press "Add" button to add a new Editable row to Grid[StudentGrid]
And then, go to StudentNo in the added row and press the "Enter" key.
I press "Enter" Key, the [StudentDialog] visible
If I put the student number and press "Enter" key in [StudentDialog], the information of the students corresponding to the grid below will be printed out (for example, if the search term is "10", students with 101, 1001, and 10 will print out as search results)
And [StudentDialog] disappears when selecting one of the rows of the retrieved results.
Insert student's information into [StudentGrid] currentEditRow, which was selected in [StudentDialog].
I am currently using html and javascript.
I'm asking you a question because I couldn't find and try data on where the current Row of grid is
and how to put the value in each column of grid's current EditRow when selected from dialog.
Please let me know if there is an example or reference for that part.

Hi,
I am using a RadGrid with a several types of columns, one of them being a GridDropDownColumn. I am having trouble setting the width of this type of column. I can get the column width smaller, but the combobox in the column does not get smaller. What is the correct way to set the width of GridDropDownColumn?
Thank you,
Mary

I have a radgrid that binds an object stored in the ViewState (Case). When I click on the radgrid's "Add" button (firing the OnInsertCommand) I get the following error: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'LookupValue'.' The specific control I am having problems with is the RadDropDownTree, and only when its definition contains this "SelectedValue='<%# Bind("LookupValue.Code") %>'"
I do not understand why this is happening. What is so different now that my radgrid is binding to a object that contains a subobject?? What do I need to be doing differently?
Just as an fyi, I do not get this error when the OnUpdateCommand fires. Below is my code.

Hello!
I was wondering, is it possible to change the icons of the export button in the footer of the radgrid? (Xls, pdf and csv).
I tried modifying their CSS classes, but did not work.
Thanks!
