IgGrid in one column, show different kinds of inputfields/Editors
posted

Hello community,
i want to hava a column in an iggrid, which is in same cases a dropdown menu in other cases an input text field.

Lets say there is table with the columns "Property" and "Value":

Property                    |                  Value

---------------------------------------------------

Currency                   |                  $

Count of something  |                   31242


For the first row it makes sense to use a dropdown list, which shows the user only valid input values, the count is limited.

For the second row you can not use a dropdown list because there is no limit of possible items of the list, the user has to enter a number with the keyboard.

So is there a way, to customize one column, so this column can be a dropdown list and sometimes an input text field?

Hopefully someone can give me a hint, because I have no idea how to start with this, I am happy for any kind of support.

    Hello Michael,

     

    You could use a conditional template to create two different spans based on the condition you want to check. Then handle the rowsRendered event that the grid raises each time it re-renders and initialize the appropriate editors. If you use the Infragistics editors instead of a regular text input and dropdown, you would benefit by having some options at your disposal that we provide you out-of-the-box.

    Please check the code sample below: I have used an igCombo editor with some dummy data for the dropdown and an igTextEditor for the input. Inside the conditional template I assign two different classes to the rows spans so I could select them with jQuery and initialize the appropriate editors:
