Hi,

I am trying to implement 3 buttons to filter a templated column in a nested grid.
So i have my buttons. I can find the column. I had the filter. I rebind .. but No filter is apply .

<telerik:GridTableView runat="server" DataSourceID="LDS" Name="PRD" AutoGenerateColumns="False" DataKeyNames="1,2,3"

ShowHeader="false" HierarchyDefaultExpanded="true" CommandItemDisplay="Top" >

<ParentTableRelation> [...] </ParentTableRelation>

<CommandItemTemplate>

<telerik:RadButton ID="RadButton1" runat="server" Text="ClearFilter" CommandName="ClearFilter" OnClick="ClearFilter">

<Icon PrimaryIconCssClass="rbCancel" />

</telerik:RadButton>

<telerik:RadButton ID="RadButton2" runat="server" Text="++++++++++++++" CommandName="Exp" OnClick="CustomFilter">

</telerik:RadButton>

<telerik:RadButton ID="RadButton3" runat="server" Text="---------------" CommandName="No-Exp" OnClick="CustomFilter2">

</telerik:RadButton>

</CommandItemTemplate>

<Columns>

<telerik:GridTemplateColumn DataField="totaldone" HeaderText="totaldone" UniqueName="SuperFilter" >

[...]

</telerik:GridTemplateColumn>

</Columns>

With in my code behind:

protected void CustomFilter(object sender, EventArgs e)

{

dude(RG_BL.MasterTableView);

}

protected void dude(GridTableView gridTableView)

{

GridItem[] nestedViewItems = gridTableView.GetItems(GridItemType.NestedView);

foreach (GridNestedViewItem nestedViewItem in nestedViewItems)

{// Let's find the grid

foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)

{

this.Label1.Text += nestedView.Name + "(" + nestedView.Items.Count + ")" + " | ";

if (nestedView.Name == "PRD")

{// Got the Grid

nestedView.FilterExpression = string.Empty;

foreach (GridColumn column in nestedView.Columns)

{// The Column ?

if (column is GridTemplateColumn && column.UniqueName == "SuperFilter")

{// Here.

GridTemplateColumn myColumn = column as GridTemplateColumn;

myColumn.CurrentFilterFunction = GridKnownFunction.GreaterThan;

myColumn.CurrentFilterValue = "0";

}

nestedView.Rebind();

}

if (nestedView.HasDetailTables)

{ dude(nestedView); }

}

I must have miss Something, If you have any idea.

Regards,

Pierre

Slow closing RadWindow in Internet Explorer

I have a RadWindow inside a RadWindowManager (with NavigateUrl) that closes really slow but only in Internet Explorer (including 11). It only occurs when the window is maximized. The problem becomes very noticeable when there are many grid items in the window. Closing takes up to 15-20 seconds. Profiling shows that the offsetWidth function in IE takes a really long time. Chrome and Firefox are instant.

I tried many configuration options and it seems that the only way to solve this issue is by not having the window maximized. Also, if I just delete the window manually, everything works quickly. Setting DestroyOnClose = true does not solve this problem either. What are the extra calculations that are happening on close event? Is there a way to avoid them?

Time picker data type validation

Hi, I am using a Time picker in my web form. The time selected is bounded with a column in the back-end database of the data type time.

When the comparison between the time selected from web app and the column of the data type time in the database, the web app gives me an error indicating that "The data types time and datetime are incompatible". I have noticed that time picker has a data type of date and time together which is making this problem.

any solution for that?
Regards.

Selected Item is restored when navigating away and then back

We have a RadTreeList that is inside an ASP.NET control. On the Page_PreRender of the control we are resetting the selected item (TreeListName.Items[0].Selected = true).

However, when we select something, navigate away from the page, and then back to the page the selected item is getting reset at some point to the selection that it was prior to navigating away. This occurs despite the fact the the selection is getting forced in the PreRender event.

I believe this has something to do with Ajax and/or ViewState. I tried turning off ViewState for the control using EnableViewState = false but the control did not render even though we are using the NeedDataSource event and there was a collection assigned to the DataSource within that event. We have always used NeedDataSource so we know that it works when ViewState is enabled.

Do you have any suggestions or advice?

Thank you.

Html based export format is not working in Excel 2010

After a security update for Microsoft Excel 2010 (KB3115322) which was released on 12 July 2016 documents using HTML based Excel format could not be opened. There is already an open discussion in Microsoft Community forums and we hope the issue will be resolved soon. Meanwhile the possible solutions are to either uninstall the update or uncheck Enable Protected View for files originating from the Internet option from Options -> Trust Center -> Trust Center Settings -> Protected View in Excel. Another option is to use some of the other Excel formats where this issue could not be observed.

Update (August 2016)

You can find below the official announcement by the Microsoft Excel Support Team about this matter and its Resolution:
Excel Workbooks may not open after installing MS16-088

Here is another reference:

Client side databound event

Hi,

On the kendo side of things there seems to be a databound event that you can subscribe to. I cannot seem to use this on the htmlchart though. I am trying to add it to the kendo widget element of the chart but it doesn't work. I am moving away from server side stuff where possible so need this to be client based.

kendoWidget.dataBound = function(e) {

alert("dataBound");

}

Any ideas?

Regards

Issue with Initial Image And Bootstrap Collapse

I'm having a problem with the initial image in my image gallery not being resized when the image gallery is placed in a Bootstrap Collapse panel. As soon as I click to scroll through the images, it works fine, but the initial image isn't resized when the panel is shown. Below is some sample code that should illustrate the problem. Any ideas on how to resolve this?

<div class="panel panel-default">

<div class="panel-heading" role="tab" id="headingOne">

<h4 class="panel-title">

<a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">Show Images

</a>

</h4>

</div>
