Hello,

Would you like to provide a simple runable sample? I am not able to run your sample due to error in your Web Method.

Webcombo is pupolate with Elements 'undefined' and after click of webcombo-button is the button unvisible.

I would need to have the runable sample to see what undefined error. Do you mean that the button of dropdown after showing the container? If yes, please try to use below code after show the container.

webcombo1.DoResize()

Regards,
Handy

Hi,

It shows undefined because you used single column from the combo mode.
You should use Multiple columns instead of single column because you already defined a Column which have a cell collection itself.
After changed it into multiple columns, it should work fine.

I had the same issue with "undefined" actually showing as the text in my webcombo. I changed to MultipleColumns and now the drop down does nothing. This is integrated in a webgrid. Do you have a sample where the webcombo is integrated into the webgrid and then depending on what is chosen in a cell, the rows in the webcombo are different?

Hello Ryan,

We don't have the similiars sample. However, we do have sample that integrate with WebGrid which runs without issue. To make it quicker, can you send us a simple runablw sample that replicates the issue? We can analyze what cause your issue from there.

Regards,
Handy
