In a Database i've stored various item entries ie. ItemName such as
abc 8"x12", xyz 4"
i've taken all the items in Radcombobox, but whenever i want the selectIndex it shows
\" added before existing " (ie. Inch in ItemName)in each selectedvalue of an ItemName, coz of that i cant get the selectindex of that item.
so my question is what is that being added to the ItemName(\") and how to remove that \" from the selectedValue to get its selectedIndex
here is my short code,

C#

RadComboBox comboBox = (RadComboBox)editItem[dtBoundColumn.ColumnName].Controls[0];
                string selectValue = comboBox.SelectedValue;
                //selectValue.Replace("\"", "");

comboBox.SelectedIndex = comboBox.FindItemByText(selectValue).Index;

I tried commented part but it didnt work.
thanks in advance.

What error messages did you get while debuging?

while debugging,in string variable selectValue i'm getting value xyz 8\"x12\" for the selected item abc 8"x12", due to this it cant find SelectedIndex for the item xyz 8\"x12\" as it is there in table with text xyz 8"x12".
I understand the backword slash may be added due to double quotes in a string, but how can neglect the backslash to get the selectedIndex?

Did you see a \" in output/UI. In code it is ok if you see.

due to that slash being added i cant get the selectedindex for that selected Item.

Is there a 'FindItemByValue()' method? Maybe you could use that instead.

Hello there :)

First of all, please, remember to specify what type of an application it is (web/windows). Sometimes it comes very handy in both figuring out your problem and providing a solution.

Okay, in C#, there are few basics I've listed below:
1. Strings are always represented within double quotes
2. A single Backslash is used as the escape character in C#
3. In order to represent a string which contains double quotes or single quotes, you have to precede each of these characters with a single back slash
4. But when displayed on screen, .Net does NOT show these back slashes

If you understand these fundamentals, you'll understand that you cannot remove backslashes that are used as escape characters from a string.

Therefore, try these steps and see;
1. Create a test page/window with a radcombobox in it
2. Put some random hard coded values with double quotes characters in it
3. Pick a value and write logic to search the control with and with back slashes for that value

One of it should work, if it doesn't, post the code so we can see what you are doing.

Hope this helps, regards
