combobox find item by value

Rakesh Kaushik

Hello Guys,
Is there any way in a combobox to find the value and display the result.

in a combobox by the value
I have combobox cmbCategory bound to tabledata i.e.
cmbCategory.DisplayMember = "categoryName";
cmbCategory.ValueMember = "categoryID";

in table Category i store the value as categoryID int, categoryName as varchar

as this combobox is on employee Entry Form. i want to modify particular employee record
for that when i pickup employee record from database through datareader categoryID
is in value based like 1 or 2.
I want to now load cmbCategory according to value ie 2 and display related categoryName

Please help me.

Sorry but this solution is not seems perfect because it gets fail when the combo display text is duplicate.

so the selection should be based on its key or composition of dispay text and value.

Then you can do like this

cmbCategory.Text = "Textvalue";

it will automatically select the index .

If you want to select the category by its text then code is
cmbCategory.SelectedIndex = cmbCategory.Items.IndexOf(cmbCategory.Items.FindByText(TextValue));

and ff you want to to select the category by its value then code is
cmbCategory.SelectedIndex = cmbCategory.Items.IndexOf(cmbCategory.Items.FindByValue(value));

thank you
