[Solved] will not bind a checkbox column in the grid

[Peter Beyer]

Dear Telerik,

We have problems implementing binding to a checkbox in a grid. We believe that we do everything the Kendo way, but it's still not working.

We have made an example were you can see our problem - may be someone in here can see, what we are doing wrong.

What you should do to see the problem: try check one or many items in the select column. Push the button "Show selected items". We have made a alert, that will display the id's that we have selected, but the alert is empty, even that we have bind the column.

Example

Thanks in advance

Hello Peter,

This happens because no binding is performed over the templates. There are a couple of ways to achieve the desired behavior:

• Use the dataBound event handler to get all items in the current view, find the corresponding checkboxes by the row's data-uid attribute and manually bind them
• Use a click event handler instead of binding, then manually set the value of the dataItem corresponding to the row

I would also recommend checking this example, illustrating similar behavior.

Thank you Alexander,

It helps us a little bit, but we still have some issues.

Checked rows doesn’t stay checked
after grouping by columns. And filtering is spinning sometimes.

Try this example, and see the attached pictures :

thanks Peter

Hi Peter,

The filtering issue occurs because the data type of the fields is not defined in the DataSource's schema.model. Persisting the selection when using grouping could also be achieved, however a slightly different approach should be used. Basically, the "view" contains grouped data, so the selected items cannot be found in that collection. I would suggest using the Grid's dataItems method instead, as shown here.

Hi Alexander,

I just talk with my developer, and he says that your implementation suggestion is working fine.

Thank you
