Dynamically created WebCombo and the ISControl_InitializeAtlas error

ArtAmurao — Mon, 29 Apr 2013 04:45:15 GMT

Hi,

We are encountering an error on our page with a WebCombo. Our WebCombo is being generated in the code, and is being added to a control under an UpdatePanel. If the UpdatePanel uses a PostbackTrigger, it works fine. However, if we use an AsyncPostbackTrigger, we are receiving the error, "The value of the property 'ISControl_InitializeAtlas' is null or undefined, not a Function object" and the WebCombo is not rendered properly. Please see attached sample page.

I can confirm that the runtime licenses are supplied correctly on our web.config and that the ISNet.dll, ISNet.WebUI.dll, ISNet.WebUI.Resources.dll are on our website's bin folder, as indicated on some of the responses to similar problems I've found on this forum. If you notice, I also tried to add the <system.webServer /> tags on our web.config. All these did not resolve the error we're encountering.

This is happening on my local machine (Windows 7, VS2010) and on our app server (Windows Server 2008, IIS7).

We need to use the AsyncPostbackTrigger in this page as we have other controls that would be affected. Please help!

Thanks!

Default Number of DropDownRows

tjp1 — Thu, 07 Mar 2013 15:11:39 GMT

I currently have a few hundred webcombo boxes in my application. I recently stumbled upon the "DropDownRows" setting which allows you to set the number of initial records loaded by WebCombo.

Is there a way to globally set this value across all my webcombo boxes? Or must I resort to manually changing the value in every WebCombo?

Webcombo clientside Row collection manipulation

sinan.biondic@gmail.com — Wed, 06 Mar 2013 14:17:28 GMT

I'm having problems retrieving row colection from webcombo. My combo is serverside binded, and in clientside pageload event I'm trying to get rows from combo. However i get nothing from method GetRows(). Applying filters is working fine but variable rows is null, and setselectedindex(1) does nothing.

function setComboFilter(idMenu) {
    var combo = ISGetObject('cmbGodina');
    var rows = combo.getRows();
    combo.ClearAdditionalFilters();
    combo.SetAdditionalFilters("[IdRedaMenu] = " + idMenu);
    combo.SetSelectedRowByValue(String(idMenu));
    combo.SetSelectedIndex(1);
}

WebCombo ClientSide databind

sinan.biondic@gmail.com — Fri, 01 Mar 2013 04:47:44 GMT

I have following code:

function success(msg) {
    var combo = ISGetObject('cmbGodina');
    var rows = combo.GetRows();
//    if(rows.length > 0){
//        for(var i = 0; i < rows.length; ++i){
//            rows.Remove(rows[i], true);
//        }
//    }

//    combo.UpdateUI();
    var dataTable = new ISDataTable();
    var idColumn = new ISDataColumn(dataTable);
    var naziv = new ISDataColumn(dataTable);
    var datumDo = new ISDataColumn(dataTable);
    var xsltFile = new ISDataColumn(dataTable);
    var procFile = new ISDataColumn(dataTable);
    dataTable.Name = dataTable.TableName = "Root";
    idColumn.Name = idColumn.ColumnName = "IdObrasca";
    naziv.Name = naziv.ColumnName = "Naziv";
    datumDo.Name = datumDo.ColumnName = "DatumDo";
    xsltFile.Name = xsltFile.ColumnName = "XsltFile";
    procFile.Name = procFile.ColumnName = "ProcFile";
    dataTable.Columns.Add(idColumn);
    dataTable.Columns.Add(naziv);
    dataTable.Columns.Add(datumDo);
    dataTable.Columns.Add(xsltFile);
    dataTable.Columns.Add(procFile);
    $(msg).find('Table').each(function (i, row) {
        $(row).find('Field').text();
        var dataRow = dataTable.NewRow();
        dataRow.Cells.GetNamedItem("IdObrasca").Value = $(row).find('IdObrasca').text();
        dataRow.Cells.GetNamedItem("Naziv").Value = $(row).find('Naziv').text();
        dataRow.Cells.GetNamedItem("DatumDo").Value = $(row).find('DatumDo').text();
        dataRow.Cells.GetNamedItem("XsltFile").Value = $(row).find('XsltFile').text();
        dataRow.Cells.GetNamedItem("ProcFile").Value = $(row).find('ProcFile').text();
        dataTable.Rows.Add(dataRow);
    });
    combo.SetDataSource(dataTable);    
    combo.DataBind();
    combo.Render();    
}

msg is xml returned by webmethod on serverside. Everything works well, but I can't clear webcombo data before i bind it to another source. the commented lines of code, when uncommented, produce error "Unable to get value of the property 'rowIndex': object is null or undefined"

this is my combo:

<iswebcombo:WebCombo ID="cmbGodina" runat="server" AllowWildCardSearch="false" Width="200" 
                        Height="20" DataValueField="IdObrasca"
                        ViewStateStorage="None" BindingOperationMode="ClientBinding" DataTextField="Naziv">
                        <LayoutSettings ComboMode="MultipleColumns" EnableAnimation="False" AlwaysShowAllRowsOnDropdown="true"

                            <ClientSideEvents  OnAfterItemSelected="cmbGodina_OnAfterItemSelected" />
                        </LayoutSettings>
                        <Columns>
                            <iswebcombo:WebComboColumn Name="Naziv" HeaderText="<%$GetString:{%00_pub_Name%}%>" BaseFieldName="Naziv" Width="200" />
                            <iswebcombo:WebComboColumn Name="DatumDo" Hidden="true" RenderOnHidden="true" BaseFieldName="DatumDo" />
                            <iswebcombo:WebComboColumn Name="XsltFile" Hidden="true" RenderOnHidden="true" BaseFieldName="XsltFile" />
                            <iswebcombo:WebComboColumn Name="ProcFile" Hidden="true" RenderOnHidden="true" BaseFieldName="ProcFile" />
                        </Columns>
                        <ClientBindingSettings DataSourceType="ClientDataSource" />
                    </iswebcombo:WebCombo>

Webcombo databind to WebMethod

sinan.biondic@gmail.com — Thu, 28 Feb 2013 08:43:15 GMT

I am trying to bind webcombo dynamically. In the page_load event on server side i don't have the information needed to load webcombo data, i have it on client-side. I saw that it was possible to bind combo to webmethod in webservice, but is it possible to bind it to webmethod on .aspx page on which the combo itself is contained.

My problem is that i need to dynamically rebind webcombo on client depending on some input. So when users clicks on different menu options I have to load different data in combo. Is that even possible, and if yes, can someone please give me a working example. I am getting data from stored procedure in sql server. Is there a way, please help!

Webcombo Conflicts With MS AJAX Extensions 1.0

tjp1 — Tue, 04 Dec 2012 12:29:00 GMT

Web Combo seems to have trouble with Microsoft ASP.Net 2.0 AJAX Extensions 1.0, found here.

If the extensions are installed I receive these errors (varies between pages):

Error: Unable to get value of the property 'documentElement': object is null or undefined (In WebCombo.js. It highlights this line: "v50372 =v2998.XmlDt.documentElement; ")

Error: Unable to get value of the property 'parentElement': object is null or undefined (Also in WebCombo.js. This time it highlights: "var v1ce37 =this.FrameObj.parentElement;")

Any ideas? Is this a documented issue that I have been unable to find? You should be able to reproduce easily.

How Disable the Enter in the WebCombo Editing?

fabdellacorte — Mon, 03 Sep 2012 12:28:05 GMT

Hi to all,

I'm using the WebCombo version 6.0.7200.100.

I have a cell of grid that contain a webcombo associated a list of products, it is configurated with EntryMode="AutoComplete" and when writing the digits, start automatically the search of products and it is OK.

Instead I should disable the event of key 'ENTER' while writing the digits of product because with configuration EntryMode="AutoComplete", the key ENTER if the response is not returned, it have a strange behaviour.

How can do it?

thanks and regards

Fabrizio

programmatically control WebCombo from vba

robertmooney01@gmail.com — Tue, 31 Jul 2012 22:55:17 GMT

I use a web-based app that includes Intersoft WebCombo. I have successfully automated various routine/repetitive tasks in IE by using Microsoft Internet Controls called from an Excel vba module. Saves me time and assures quality.

Up to now I have been interacting with standard IE controls - text boxes, buttons, etc. But now I need to select an option from an Intersoft WebCombo. Is there any documentation or examples that would show me how this is accomplished?
