Speed issue with Intersoft MultiSelection Webcombo

Hi,

Using multiple selection should not reproduce the error. In fact, my sample also used that. What i was trying to tell you that those properties would not work well in multiple selection because it is only triggered once af the first selection. Please ensure you have applied the latest hotfix.

Handy

Hi Hiren,

Sorry for waiting. Here is my sample. If you use MinimumCharToRequest properties, it would do query for your database and populate data.
Unfortunately, this only works for single selection. In Multiple selection scenario, it only works for the first selection.
You can see my simple sample. It also handles the query itself. So, i think you will also need to figure out how to populate your data by query manually by setting AllowAutoQueryHandler false. Hope this helps.

Regards,
Handy

The page would very long respond or slowly to load data because the amout is 200000. In fact, we don't suggest to load so many records in WebCombo. To avoid this issue, I suggest not to load all data by handling them by query. Also, we have 'MinCharsToRequest' in WebComboDesigner>>Advanced Settings properties. After user typed some chars, get and implement them into query for loading data.

I am using intersoft multi selection webcombo in one of my application. I need to bind Approx. 200000 records with webcombo and to do this my page will be hang up.

Webcombo version : 4.0.7200.211

Technologies : .Net 2005 (vb)

Below is the code that I used to bind webcombo.

ASPX :

<iswebcombo:WebCombo ID="wcJob" runat="server" Width="150px" DataTextField="ShowId" TabIndex="8"

DataValueField="idSurvey" EnableViewState="false" LayoutSettings-TextBoxMode="Editable">

</iswebcombo:WebCombo>

Code File:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

wcJob.MultipleSelectionSettings.SeparatorChar = ";"

wcJob.MultipleSelectionSettings.Enabled = True

wcJob.MultipleSelectionSettings.AllowBrowseAll = False

wcJob.MultipleSelectionSettings.AutoPositionResultBox = False

End Sub

Protected Sub wcJob_InitializeDataSource(ByVal sender As Object, ByVal e As ISNet.WebUI.WebCombo.DataSourceEventArgs) Handles wcJob.InitializeDataSource

Dim objJob As New clsSurveys()

Dim dt As DataTable = objJob.GetJobNumberByIdSite(" idSite = " + getIdSite.ToString()) ‘Return 200000 records.

wcJob.ClearCachedDataSource()

wcJob.PopulateUnboundData(dt, True) ‘Code is hang up here.

objJob = Nothing

End Sub

Please help me out where I am wrong . What can I do to stop, hang up my page.
