Compare item in dropdownlist with string

[calvin]

I want to validate all items in dropdownlist with string/label.
So, I try to write like this:

If dropdownlist.Items.<u>Contains(label.text)</u> Then
.
.
.

But I get an error of "Value of String cannot be converted to System.Web.UI.WebControls.ListItem"

Does anybody know how to convert it??

Thank you for any help.

In fact I want to know does the dropdownlist contain the value same as label.text

For example If the label.text = "Hello world", check the dropdownlist contain the item "Hello world" or not.

.FindByText is, I think, what you're looking for. This function returns null (Nothing) if it doesn't find an item.

I'll try this in VB, but don't yell at me if the syntax is wrong. I'm not sure if != is "not Equal" in VB...:)

</CODE>

There is also a FindByValue which will find something based on the value of the ListItem.

Contains method is expecting System.Web.UI.WebControls.ListItem as the input parameter

In order to get the item name, you'll have to look at

DropDownList.Items(0).ToString

You may need to loop through it.
