Set value to a Hidden field.

Hello,

I am sorry for the inconvenience and I sorry for the late response.

I made simple hierarchical WebGrid and try to show the column of child tables.

But unfortunately, I can’t show/hide the child table’s column as well.

If you wish to, I will forward this scenario to the developer team as a feature request.

Thank you for your understanding.

Regards,

Hans.

Thanks for your Sample Hans.

I cant use

WebGrid1.RootTable.Columns.GetNamedItem("CompanyName").Show();

because the Contact_ID is in the second childTable. The Roottable has 3 childTables.

Region(RootTable) ->City(ChildTable) -> Building(ChildTable: HERE IS the CONTACT_ID) ....

How can i access that column?

I tried

grid.RootTable.ChildTables[0].ChildTables[1].Columns.GetNamedItem("CONTACT_ID").Show();

but i does not work. What iam doing wrong?

Hello,

I am sorry for the inconvenience. This issue occurs due to the WebGrid can’t get the object of column/cell that you hide.

I have workaround that you might try.

I made simple WebGrid sample and bind to access data source (Northwind.mdb database and Shippers table).

In my sample, I hide the CompanyName column through javascript code (in window onload).

I also add two buttons to the page sample.

The first button is to set new value in CompanyName column.

Before I set the new value to CompanyName column, I show the CompanyName that I hide in window onload.

This step is to get the object from CompanyName column.

After that, I hide the CompanyName once again.

The second button is to get the CompanyName value.

Please kindly have review on my sample and let me know your response.

Regards,

Hans.

I have a Grid with 5 columns. The relevant columns are MEETINGPLACE and CONTACT_ID.

Column MEETINGPLACE is a Webcombo. If i click on the Webcombo, the Webcombo loads a table. In that Table i assigned a CONTACTPERSON to a PLACE.

Now if i choose that Contactperson the webcombo puts the PLACE in MEETINGPLACE column and the ID of the CONTACTPERSON in the CONTACT_ID column. So far so good.

For that i added these two lines in a Javascript

grid.GetSelectedObject().ToRowObject().GetCell('CONTACT_ID').SetValue(wcDivision.Value, true);
        grid.GetSelectedObject().ToRowObject().GetCell('CONTACT_ID')SetValue(wcDivision.Value);

The CONTACT_ID Column is visible. If it is Visible it all works fine. But if i set the column CONTACT_ID to visible=false javascript cant set a value to that column, because its hidden

Is there a workaround for that? Or do have someone an idea, how to fix that?

Thanks
