Hi,

ViewState errors can occur if Control tree is different between requests
Please provide test sample which we can test localy

The test localy works

Hi,

If you remove PageProxy then data request will not be initiated.
Try to initiate any direct event and i guess you will get the same ViewState error

Just investigate what difference in the code behind logic during ajax requests, i think i don't recreate controls (or recreate it in the different sequence)

[ViDom]

I have found a problem. Excuse for troubling.

protected override void OnInit(EventArgs e)
{
	if (this.StoreMain.Reader.Count == 0)
	{
	    JsonReader StoreFields = new JsonReader();
	    StoreFields.Fields.Add(
		new RecordField()
		{
		    Name = "Id",
		    Type = RecordFieldType.Int
		});
	    StoreFields.Fields.Add(
		new RecordField()
		{
		    Name = "Name",
		    Type = RecordFieldType.String
		});
	    StoreFields.IDProperty = "Id";
	    this.StoreMain.Reader.Add(StoreFields);
	}
	if (!X.IsAjaxRequest)
	{
		if (this.GridPanelMain.ColumnModel.Columns.Count == 0)
		{
		    ColumnCollection ColumnsList = new ColumnCollection();
		    ColumnsList.Add(
			new NumberColumn()
			{
			    DataIndex = "Id",
			    Header = "ID",
			    MenuDisabled = true
			});
		    ColumnsList.Add(
			new NumberColumn()
			{
			    DataIndex = "Name",
			    Header = "Name",
			    MenuDisabled = true
			});
		    this.GridPanelMain.ColumnModel.Columns.AddRange(ColumnsList);
		}
		this.StoreMain.BaseParams["limit"] = "={" + GlobalSettings.pageSize.ToString() + "}";
		this.PagingToolbar1.PageSize = GlobalSettings.pageSize;
	}
}

Hi,

Please clarify why did you use it?

if (!X.IsAjaxRequest)

I can't see any needs to don't execute that code during Ext.Net AjaxRequest (DirectEvent/DirectMethod).

I don't know. Because so it works.
During AjaxRequest the GridPanel has columns and it is not necessary to generate them.

[Daniil]

OnRefreshData handler is DirectEvent.

It uses .BaseParams. So, please move

this.StoreMain.BaseParams["limit"] = "={" + GlobalSettings.pageSize.ToString() + "}";

out of

if (!X.IsAjaxRequest)

[ViDom]

ok, thank you
