There are two ways to set the initial value with ComboBox V3. One way is to set the value of the textbox. However, if your data is complex with multiple columns, or you want to pick from the actual dataset, you will want to use the new InitialSearch feature.
Method 1: Set the Textbox Value
Use the Value attribute in the ComboTextBox tag. Note that this merely sets the value contained by the textbox, and does not actually select an item from the list.
eg:
Method 2: Setting the InitialSearch (Selecting a value from the dataset)
In many cases, we need to actually select a record from the dataset. How do we choose a record from a dynamic recordset without:
Without writing new serverside code to look for a specific record
Without knowing the record information at runtime?
The answer is InitialSearch. This is like pre "typing" a string into the textbox, and then selecting the most likely result. Therefore it is not necessary to write out the entire string. Even 1 letter is enough to select a record, but the more letters you type of the string, the more accurate the selection will be.
