How to delete the child Table header when the child table data is empty?

Hello,

Thank you for your sample.

After I investigated you code, it seems the issue persist due to mistakenness in your code.
You already define the WebGrid’s structure from the beginning you create the WebGrid.
Therefore, you couldn’t delete the structure just by using this code:

WebGrid1.LayoutSettings.Hierarchical = false;WebGrid1.ClientAction.RefreshModifiedControls();

And as far I know, you couldn’t delete table by using this query code:

string StrSql = "Delete from Schedules ";

However, if want to make any changes in your WebGrid’s structure.
I recommend you to create the WebGrid’s structure programmatically.
With this scenario, you could have more dynamic WebGrid’s structure.

Regards,
Hans.

Hello,

Yes, you could. You should set “ChildRowEmptyAction” property to “HideChildContent”.
Then set a validation in OnAfterResponseProcess() client side event.
Here’s the snippet code in OnAfterResponseProcess():

function WebGrid1_OnAfterResponseProcess(controlId, actionName, lastRequestObject, xmlResponseObject) {    var WebGrid1 = ISGetObject(controlId);
    if (actionName == "DeleteRow") {
        var childRowsLenght = lastRequestObject.GetParentRow().GetChildRows().length;
        // if there is no child row any more
        if (childRowsLenght == 0) {
            // we need to refresh the WebGrid to apply the ChildRowEmptyAction property
            WebGrid1.Refresh();
        }
    }
    return true;
}

Also “RestoreExpandedChildRows” property to “True” and “RestoreRowSelection” to “All”.

Hope this helps.

Regards,
Hans.

Hi,

When I use RootTables and ChildTables, when the childTables has data,it shows the data,but when I delete all of the childTables data, now it shows the header only in childTables,I wonder if it could realize that the childTables'header should hide because the childTables'data is empty. but I don't konw how to realize it. I konw set the Hierarchical="true" it support master and detail table show,but set Hierarchical="false", it didn't show that, but in the behind code when I set Hierarchical="false",it also show the Hierarchical propertity. so could you please give me a hand?
