IE freeze after webgrid filter

jelsner1976@gmail.com — Thu, 02 Jun 2011 09:17:20 GMT

I have a grid defined as below on a couple different pages.  On one of the pages that uses this, IE 8 will freeze up after they perform a filter on one of the columns.
This only happens for certain users.  Are there any IE settings, add-ons, etc. that I should look for that can cause this behaviour.
Again it works fine for most users, it is only some users and only one of the pages that uses the grid as defined below.
The other pages use the same code and it works fine.

Blend Crashes after upgrading from ClientUI 3 to 4

I upgraded my ClientUI from 3 to 4 today and now when I open my project in Blend, it crashes with the following log information:

WebGrid: disappearing columns and scrolling slider locked

Eric — Tue, 21 Dec 2010 05:24:16 GMT

Hi,

I have created a demo-project for you which shows the problems. Please see attached ZIP.

Please include the Intersoft framework 3.0.5000.705, WebGrid 6.0.7200.220, System.Web.Extensions.dll 1.0.61231.0, AjaxControlToolkit.dll 1.0.10606.0, AJAXExtensionsToolbox.dll 1.0.61025.0 in order to get the same results. Please also set the .NET Target Framework to 2.0.

To reproduce the problem:

select in the dropdown "ABC" and click refresh button
in the upper WebGrid make the first column wider (resize it)
click on any row in the upper WebGrid

Now the application crashes trying to access grdUpper.RootTable.Columns.GetNamedItem("D"). Please note that the first column is only set to Visible=false, never it's missing.

Also, this only happens if the first column is resized. If not touching this, it works.

As an additional bug, in the lower grid the slider to move between different pages doesn't work. Only the + and - buttons move the slider.

My questions:

Can you confirm these two bugs?
Will there be a hotfix for it?
Do you know of any workaround possible?

Regards,

Eric

How to enable / disable freezing depending on data

Eric — Fri, 03 Sep 2010 09:41:51 GMT

There is a related sample in this thread: http://www.intersoftpt.com/Community/WebGrid/WebGrid-crash-scrolling-freeze-column-hidden/

When I have no data for the grid, I want to hide all columns, create my own dataset add a row and write the text "no data" into this first row's first column. This is done in the InitializeDataSource event.

In PreRender event I check if there is only this one row with this special text. If yes, I hide all columns (now works after you fixed the crash mentioned in the other thread).

Problem is now that I cannot dynamically enable/disable the column freezing. For normal display, I want the first column to freeze (not modifiable by user). But when I hide all columns when no data is present, I get the error message "Freeze Pane cannot be activated on this column because it has exceeded the maximum size of scrollable viewport."

I assume this is because there is nothing to show (message is probably slightly wrong). So I should disable the frozen columns in the PreRender event somehow. I couldn't get that working. Or leave freezing away in aspx page and enable it for normal data.

In grid's LayoutSettings I have:

<FreezePaneSettings AbsoluteScrolling="true" ActiveFrozenColumns="1" MaxFrozenColumns="1" ShowSplitterLine="False" /> In PreRender I tried to disable these values without success. I also tried leaving the above tag away and adding these values in PreRender.

I also tried to set/change the value grdResult.LayoutSettings.AllowColumnFreezing. But that caused WebGrid to crash in some JavaScript.

How do I disable/enable column freezing depending on the data I have?

WebCombo 4 Client Calls SetSelectedIndex And SetSelectedRowByValue Fail Crash

PRISMAY — Fri, 08 Jan 2010 09:18:58 GMT

I have a custom date control made of 3 components: WebCombo and two WebInput calendars. The WebCombo gives the user a preset number of options that automatically set the calendars, i.e., Yesterday, Last Week, This Month, etc.

When the user directly sets the dates via the calendars, then we want to automatically set the combo's range type selection to our "Custom" selection. I'm doing that via a workaround using the code below:

oIsCbo.SelectedIndex = i;
oIsCbo.SetValue(oDRT.dateRangeTypeId);
oIsCbo.SetTextBoxValue(oDRT.dateRangeTypeName);

I'm using this workaround because both SetSelectedIndex and SetSelectedRowByValue crash when called. Both calls cause the javascript runtime error of "'this.Column.BaseFieldName' is null or not an object." I'm using an unbound combo and all the UI elements do not post back so everything is done client-side. We don't want a simple control like this to constantly post back on every little user change.

Here's how our PrismComboBox (derives from ISNet.WebUI.WebCombo.WebCombo) is set up:

this.AllowWildCardSearch = true;
this.EnableViewState = true;
this.Items = new PrismComboBoxItems();
this.Items.ComboBox = this;
this.SelectedItem = new PrismComboBoxSelectedItem();
this.SelectedItem.ComboBox = this;
this.LayoutSettings.AllowAddItem = false;
this.LayoutSettings.AllowFloatingText = false;
this.LayoutSettings.AllowNavigationOnMouseWheel = true;
this.LayoutSettings.AllowTextWrapping = false;
this.LayoutSettings.AlwaysShowAllRowsOnDropdown = true;
this.LayoutSettings.AlwaysShowColumnHeaders = false;
this.LayoutSettings.AlwaysShowHelpButton = false;
this.LayoutSettings.AlwaysShowResultBox = false;
this.LayoutSettings.AlwaysShowSearchButton = true;
this.LayoutSettings.AutoColumnOrdering = false;
this.LayoutSettings.ComboMode = ISNet.WebUI.WebCombo.Mode.SingleColumn;
this.LayoutSettings.EnableAnimation = true;
this.LayoutSettings.EnableSlidingAnimation = true;
this.LayoutSettings.EntryMode = ISNet.WebUI.WebCombo.EntryMode.AutoComplete;
this.LayoutSettings.NoResultFoundAction = ISNet.WebUI.WebCombo.NoResultFoundAction.RevertSelection;
this.LayoutSettings.SearchIconMode = ISNet.WebUI.WebCombo.SearchMode.Text;
this.LayoutSettings.TextBoxMode = ISNet.WebUI.WebCombo.TextboxMode.Editable;
this.UseDefaultStyle = false;
this.SelectionRequired = false;

Here's how the combo box is further configured and populated in our PrismDateRange control:

m_ComboboxRangeType.ID = "ComboBoxRangeType";
m_ComboboxRangeType.AutoPostBack = AutoPostBack;
m_ComboboxRangeType.SelectedIndexChanged += new EventHandler(m_ComboboxRangeType_SelectedIndexChanged);
m_ComboboxRangeType.PreRender += new EventHandler(m_ComboboxRangeType_PreRender);
m_ComboboxRangeType.Enabled = this.Enabled;
m_ComboboxRangeType.DropDownRows = 50;

I've attached a couple falsh videos of the issue while running in debug mode. The first one shows the crash when SetSelectedIndex is hit and the value of this.Column. The second one breaks into my javascript code and also shows the result of SetSelectedRowByDefault in the watch window as well as continuing on and the crash of SetSelectedIndex.

As you can see above, the BaseFieldName is set up so I'm not sure why all that is empty on the client side, i.e., this.Column and so on. Let me know if you need anything else.

I'm in a bind to get this working please so I can really use a fast resolution. Thanks a lot.

WebGrid crashes when scrolling with column freeze and setting a column hidden

Eric — Fri, 08 Jan 2010 08:43:18 GMT

I experience that WebGrid crashes, when the user horizontally scrolls. This happens only when I set the first column to be frozen. It also only happens when I set some columns to hidden (Visible=false).

Attached is a simple sample in VB.NET for that (remove the .txt in the file names). Simplified, the sample contains:

An aspx file with the WebGrid "grdResult" and the columns "Description", "X1", "X2",..."X9"
<FreezePaneSettings AbsoluteScrolling="true" ActiveFrozenColumns="1" MaxFrozenColumns="1" ShowSplitterLine="False" />
In the aspx.vb code file there is a handler for InitializeDataSource which adds some static data to show, so that the grid is not empty
In the handler PreRender I change some column titles (from X1 to C1 etc.) and set two columns to Visible=False

When scrolling, it crashes with: "Microsoft JScript runtime error: 'parentElement' is null or not an object" (Break/Continue/Ignore). The debugger then stands on this JScript code: "var v1d119 =vfcb75.parentElement" (and vfcb75 is null).

I believe this is a bug in WebGrid. We are using the newest WebGrid 6.0.7200.218 and Framework 3.0.5000.705 and the users use Internet Explorer 6 to browse the page.

Can you confirm that this is a bug? If yes, will there be a hotfix available soon? Is there any workaround except not to use freezing or hiding?
