In a situation where the user wants to add a new row to the gridview control, I have assigned some default values for the new row. For some of these default values, I want to prevent the user from changing those values. Am I able to do this? If yes, how can I do this? Please provide code?
Thanks.
Thanks.

Assume I have the following two tables:
Table 1 (Customer) has the following fields:
1) Customer ID
2) First Name
3) Last Name
4) Street Address
5) City FK
Table 2 (City) has the following fields:
1) City PK
2) City
Table 2 is a look-up table that consists of city names. City PK if the primary key field for the City table. These primary key values appear as foreign key values in the City FK field of the Customer table.
I want to add a grid view to a form which shows all of the data in the Customer table. Instead of showing the foreign key values in the City FK field, I want to show the actual city name which corresponds to the foreign key value stored in this field. How can I do this with the grid view control?
I had placed a grid view on a form and had attached a data set to this control, but the the City column is showing foreign key values for the city instead of the city name. This is what I don't want the grid view to show. How can I resolve this problem?
Thanks.

The MultiColumn Combobox will display "Telerik.WinControl.." if the value of Display Member is null or empty. That's wrong.
Please see 1.jpg.
It should be display a empty string.
Please help me!

Hello, I went through and created a custom visual item for my listview and everything worked out great (Telerik documentation was a big help). I then tried to apply custom grouping to my listview and no grouping appeard (everything loads, just without groups). After another quick look I realized that my custom item is also being applied to the group item (doh!). How would I go about determining the type of item being created int the VisualItemCreating event? Thanks

Hello
I have looked through the forums and I haven't found an answer that works yet so I thought I would just ask. I am trying to make the first row of my radgridview object have a blue background color in c#. This is some of the code
foreach (var ResultLine in myFiles)
{
string[] Contents = System.IO.File.ReadAllLines(ResultLine.FullName.ToString());
if (headercount == 0)
{
string HeaderRow = Contents[0];
string[] HeaderRowSplit = HeaderRow.Split(new char[] { ',' });
for (int i = 0; i < rgvAlarmLog.ColumnCount; i++)
{
rgvAlarmLog.Rows[rowCount].Cells[i].Value = HeaderRowSplit[i];
rgvAlarmLog.Rows[rowCount].Cells[i].Style.BackColor = System.Drawing.Color.Blue;
}
rowCount++;
headercount = 1;
If I change backcolor1 or 2 or 3 then I see color change in the highlighted row when selected. I do not want that though. I want the background color to be blue all the time. How can I do this with code?
