Hello

It's working on my PC the same as your video show, but when I set ClientSideBinding with Reuse server datasource option, I ve got error System.NullReferenceException in my web browser. Next when I insert manually section like this:

it's working ok

My ver: WebGrid build 401 and Framework build 751

Hi,

So we have two solutions:

1. by using DataSourceID , then use RegisterStartupScript with JS code which set WebComboProduct Value on the client side and make LoadValue on it

2. by using DataSource (with or without AllowAutoQueryHandler depend on how many rows we expected), then in "FormView1_ItemCreated" set DataSource property to your customdata before or after setting Value on WebComboProduct.

In your example we shouldn't use clear "select * from Products"

I think it should be some method to retrieve list of WebCombo on demand (when the DataSourceId is in use). As you've seen the ClearCachedDataSource not working properly.

Hi,

Your example explain how to refresh WebCombo on the client side

Maybe I'm not writing clearly or you don't read carefully.

I don't accept method like this:

 this.ClientScript.RegisterStartupScript(......

in FormView1_ItemCreated on the server side

I'd like to refresh (prepare) WebCombo in FormView1_ItemCreated before (or after) setting his Value.

Your method  WebCombo1.ClearCachedDataSource(); just not working.

I've tried (copy of my first example):

protected void FormView1_ItemCreated(object sender, EventArgs e)
    {
        if (FormView1.CurrentMode == FormViewMode.Edit)
        {
            DataRowView rowView = (DataRowView)FormView1.DataItem;
            if (rowView != null)
            {
                //test binding
                WebComboCategory.Value = "2";//Condiments
                WebComboProduct.ClearCachedDataSource();
                //ISDataSourceList.Tables.GetNamedItem("Products").ClearCacheAndData();
                //ISDataSourceList.Tables.GetNamedItem("Products").Select();
                WebComboProduct.Value = "3";//Aniseed Syrup
            }
        }
    } 

My question is : How can I manually refresh WebCombo on the server side ?

I've found solution:

In Application Poll Advance Settings set: Enable 32-Bit Applications= True

We prefer also Identity=NetworkService

Hi,

I'm sorry, but I don't understand. Where would you like to set WebComboProduct.Value to "3" or other value comming from datasource (which is binding to FormView )  ?

We use similar solution with RegisterStartupScript, and set WebComboProduct on the client side, but it's workaround.

Is there no other way ? ... Intersoft have to do that :-)

Andrzej
