Using a WebDataGrid and ExcelStyle filtering... version 15.2
I am having an issue between filtering and paging. I have a couple of scenarios that should work but I can't get them to work with the same configuration.
The issue when my WDG is configured as such....
enableviewstate=trueenabledataviewstate=trueenableajax=falseenableajaxviewstate=false
Working with a grid that's 3 pages...
I can filter to a 2 page dataset... paging works, clear filter works.
When I filter to a 1 page dataset, there is no paging (correct), but when I clear filter, it returns to the full dataset, but the paging does not return (should be 3 pages as it is on page load).
So I reconfigure my WDG settings as such...
enableviewstate=falseenabledataviewstate=falseenableajax=trueenableajaxviewstate=true
Using the same 3 page grid/dataset...
I filter to the 1 page dataset
No paging (correct) and when I clear filters it goes back to the full dataset (3 pages worth) and the paging buttons return.
When I filter to the 2 page dataset..
Filter works, but clicking on page 2 restores the grid to the full dataset (3 pages worth) instead of page 2 of the filtered dataset.
I need both of these scenarios to work but I can't figure out the WDG configuration required.
Ideas?
Hi Greg,
Thank you for the information shared, though it is not enough to make assumptions on the issue. An important role in the grid behavior would be how you bind the grid - keeping enableDataViewState to false requires that you bind the grid on each postback - please make sure you follow this.
Furthermore, setting enableViewState to true is not a recommended approach as this feature is known to result in misbehaviors in many situations. A lot of bugs have been fixed though, and what you experience in 15.2 is pretty probable to be working fine in 18.1.
ExcelStyleFiltering in combination with enableDataViewState to true is also a combination that is not recommended. We always recommend users to turn off those features or use them only if they are sure what they want to achieve.
I could be able to help you if you provide me with a sample that I can run on my side and investigate. If there is a bad configuration of the grid I would be able to help you with that, but if it is a bug in our code that leads to those results, then you would need to upgrade to a newer version of our product as 15.2 support has expired.
Looking forward to hearing from you.
Hi Hristo, thanks for the response.
The grid is bound on each postback.
Here is the grid control:
<ig:WebDataGrid ID="wgAdminTables" runat="server" AutoGenerateColumns="true" ClientEvents- AJAXResponse="grid_Response" OnRowDeleted="wgAdminTables_RowDeleted" OnDataFiltered="wgAdminTables_DataFiltered" OnRowUpdating="wgAdminTables_RowUpdating" OnRowsDeleting="wgAdminTables_RowsDeleting" OnRowAdding="wgAdminTables_RowAdding" OnDataFiltering="wgAdminTables_DataFiltering" OnRowUpdated="wgAdminTables_RowUpdated" OnRowAdded="wgAdminTables_RowAdded" AjaxIndicator-BlockArea="Control" OnPageIndexChanged="wgAdminTables_PageIndexChanged" OnColumnSorted="wgAdminTables_ColumnSorted" EnableViewState="false" EnableDataViewState="false" EnableAjax="true" EnableAjaxViewState="true">
<Behaviors> <ig:Activation Enabled="true" ActiveRowCssClass="selectmode"></ig:Activation> <ig:Selection RowSelectType="Single" CellClickAction="Row" Enabled="true" SelectedRowSelectorCssClass="selectmode"></ig:Selection>
<ig:EditingCore> <Behaviors> <ig:CellEditing EditCellCssClass="editmode" EditModeActions-MouseClick="Double" CellEditingClientEvents-ExitedEditMode="grid_DoUpdate" Enabled="true"></ig:CellEditing> <ig:RowAdding Alignment="Bottom" EditModeActions-MouseClick="Single" Enabled="true" AddNewRowCssClass="addnew"></ig:RowAdding> <ig:RowDeleting Enabled="true" ShowDeleteButton="true"></ig:RowDeleting> <%--<ig:RowEditing Enabled="true" EditCellCssClass="editmode" EnableDialog="true" RowEditingClientEvents-ExitedEditMode="grid_UpdateWarning"></ig:RowEditing>--%> </Behaviors> </ig:EditingCore>
<ig:RowSelectors Enabled="true"></ig:RowSelectors> <ig:Paging PagerAppearance="Bottom" QuickPages="5" PageSize="20" Enabled="true" PagerMode="NumericFirstLast"></ig:Paging> <ig:Sorting SortingMode="Single" Enabled="true"></ig:Sorting> <ig:Filtering Enabled="true" EditModeActions-MouseClick="Single" FilterType="RowFilter" EnableInheritance="true"></ig:Filtering> </Behaviors> </ig:WebDataGrid>
The grid is bound in code behind (on every postback). The row adding, edting, and deleting is handled in code behind.
The grid is also bound again in code behind for the filtering event:
Dim ds As DataSet = CType(wgAdminTables.DataSource, DataSet) Dim dt As DataTable = ds.Tables(0)
For Each colFilter As Infragistics.Web.UI.GridControls.ColumnFilter In e.ColumnFilters dt.Select(colFilter.Condition.GetFilterRuleString(colFilter.ColumnKey)) Next
wgAdminTables.DataSource = dt wgAdminTables.DataBind()
Let me know if you need any other info.
Thank you for the configuration shared.
I see some differences in the behavior between 15.2 and 18.1 and between RowFilter and ExcelStyleFilter, Please confirm if I should be investigating RowFilter or ExcelStyleFilter. I will soon publish more results from my investigation.
Any ideas on this? I downloaded the latest 18.1 release and the issue persists.
Hello Greg,
I've created a sample that mimics your scenario in order to investigate the described issue on my local environment.
Could you please have a look at it, maybe I am missing something, because everything is working fine.
Steps to reproduce:
1. Filter "id" column Equals 2
2.Only one row (with id=2) will be present in the grid
3. Paging is indicating 1 page
4. Clear filter
5. All rows from the data source are loaded and paging is indicating 2 pages
As you can see in the provided sample I have:
- Row Updaring, Deleting and Updaring
- Server side binding of data
- EnableViewState and EnableDataViewState set to "true"
- EnableAjax and EnableAjaxViewState set to "false"
As Hristo explained using of EnableViewState and DataViewState is causing some troubles in certain configuration and we strongly recommend not to use them.
Could you let me know what am I missing from your scenario.
Looking forward to your reply
