Adding an empty value to adropdownprovider gives ASYNCRequest failure

Prabha Narahari posted over 8 years ago

Hi all,

I am using the following code in pageload of my usercontrol where infragistics is used.

In Page_Load()

DropDownProvider Statusddl = new DropDownProvider();
Statusddl.ID = "Statusddl_" + editcolumns.IndexOf(assignedToColumnSetting).ToString();
Statusddl.EditorControl.Items.Add(new Infragistics.Web.UI.ListControls.DropDownItem(""));
this.UltraWebGrid.EditorProviders.Add(Statusddl);
switch (assignedToColumnSetting.ColumnKey)
{

case "Logic Status":
foreach (string dv in BLDomain.GetDomainValueListByDomainName("Logic Status", this.CurrentLibraryId))
Statusddl.EditorControl.Items.Add(new Infragistics.Web.UI.ListControls.DropDownItem(dv));
break;
case "Logic1 Status":
foreach (string dv in BLDomain.GetDomainValueListByDomainName("Logic1 Check Status", this.CurrentLibraryId))
Statusddl.EditorControl.Items.Add(new Infragistics.Web.UI.ListControls.DropDownItem(dv));
break;
case "Logic2 Status":
foreach (string dv in BLDomain.GetDomainValueListByDomainName("Logic2 Check Status", this.CurrentLibraryId))
Statusddl.EditorControl.Items.Add(new Infragistics.Web.UI.ListControls.DropDownItem(dv));
break;
case "PhySym Status":
foreach (string dv in BLDomain.GetDomainValueListByDomainName("Physical Status", this.CurrentLibraryId))
Statusddl.EditorControl.Items.Add(new Infragistics.Web.UI.ListControls.DropDownItem(dv));
break;
case "iPN Status":
foreach (string dv in BLDomain.GetDomainValueListByDomainName("IPN Status", this.CurrentLibraryId))
Statusddl.EditorControl.Items.Add(new Infragistics.Web.UI.ListControls.DropDownItem(dv));
break;
default:
Statusddl = ddl;
break;

}
assignedToColumnSetting.EditorID = Statusddl.ID;

Now in UI of my user control the definition of webdatagrid is as follows

EnableRelativeLayout="false" HeaderCaptionCssClass="GridHeaderCaption"
OnInit="UltraWebGrid_Init" onrowupdated="UltraWebGrid_RowUpdated" OnRowUpdating="UltraWebGrid_RowUpdating" OnColumnMoved="UltraWebGrid_ColumnMoved"
EnableAjax="true" EnableAjaxViewState="true" EnableDataViewState="True" OnColumnResized="UltraWebGrid_ColumnResized" OnColumnSorted="UltraWebGrid_ColumnSorted">

<ig:Sorting >

The RowUpdating method

protected void UltraWebGrid_RowUpdating(object sender, RowUpdatingEventArgs e)
{
string requestId = e.Values[MyQueueConst.REQUEST_ID].ToString();
//Get the Column name being Edited
string colname = string.Empty;
string assignedTo = string.Empty;
foreach (DictionaryEntry entry in e.OldValues)
{
if (e.Values.ContainsKey(entry.Key) && e.Values[entry.Key].Equals(entry.Value))
{
continue;
}
else
colname = entry.Key.ToString();
}
assignedTo = e.Values[colname].ToString();
int iRequestId = Int32.Parse(requestId);

BLRequest.UpdateRequestAssignmentForASPNET(iRequestId, colname, assignedTo, this.CurrentLibraryId, this.CurrentUser);

//Update the datasoure
DataRow currentRow = this.HomeGridDataSource.Select(MyQueueConst.REQUEST_ID + "=" + requestId).FirstOrDefault();
currentRow[colname] = assignedTo;

this.UltraWebGrid.DataSource = this.HomeGridDataSource;
this.UltraWebGrid.DataBind();

}

Now, when I try to edit the dropdown from the Infragistics Grid UI I get the following Error, especially since I am adding the Empty entry in my dropdown provider

Async request failed
