Problem with grouping when applied virtual scroll paging

I have created a web page in which I placed a rad grid and set the virtual scroll paging property to true,so when I group a grid by a column in which group consumes more than 1 page so instead of showing records list in collapse manner, it shows space of records consumed by that group which should not be happened instead of this it should show records list in the collapse manner and not the space of records consumed by that group. The code for aspx page is as follows:-

<telerik:RadGrid ID="rgFITList" runat="server" AllowSorting="True"

TabIndex="3" EnableTheming="False" ShowGroupPanel="True" OnItemCommand="rgFITList_ItemCommand"

OnSortCommand="rgFITList_SortCommand" OnGroupsChanging="rgFITList_GroupsChanging"

EnableHeaderContextMenu="True" onitemdatabound="rgFITList_ItemDataBound"

GridLines="None" DataSourceID="ODS_FITList"

AllowPaging="true" PageSize="40" AllowCustomPaging="true">

<MasterTableView AutoGenerateColumns="False" DataKeyNames="FITID"

GroupsDefaultExpanded="False" GroupLoadMode="Client" Name="Master"

DataSourceID="ODS_FITList">

<telerik:GridBoundColumn DataField="FITID" HeaderText="Task ID" SortExpression="FITID"

UniqueName="FITID">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="DateSubmitted" HeaderText="Submitted" SortExpression="DateSubmitted"

UniqueName="DateSubmitted" DataFormatString="{0:MM/dd/yyyy}">

</telerik:GridBoundColumn>

UniqueName="FITTitle">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FITDescription" HeaderText="FITDescription"

UniqueName="FITDescription" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UserName" HeaderText="Assigned To" SortExpression="UserName"

UniqueName="UserName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Status" HeaderText="Status" SortExpression="Status"

UniqueName="Status">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="DateDue" HeaderText="Due" SortExpression="DateDue"

UniqueName="DateDue" DataFormatString="{0:MM/dd/yyyy}">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="RankID" HeaderText="RankID"

UniqueName="RankID" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Priority" UniqueName="Priority" Groupable="false">

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</EditFormSettings>

</MasterTableView>

</ClientSettings>

</FilterMenu>

Reminder Pop Up

Hi. I am using the 2009.3.1401.35 version of telerik controls and I am trying to add a reminder to the scheduler which appears that it's not supported in this version. Is there any turn around for this issue?

Thank you very much for your help.

Full class path as ASPX element tag

v2010.3.1215.35

I drop a RadAjaxManager on a form. Then I use Configure Ajax Manager to set updated controls. The result looks like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik.web.ui.ajaxsetting ajaxcontrolid="RadAjaxPanel1">

<updatedcontrols>

<telerik.web.ui.ajaxupdatedcontrol controlid="RadAjaxPanel1">

</telerik.web.ui.ajaxupdatedcontrol>

</updatedcontrols>

</telerik.web.ui.ajaxsetting>

</AjaxSettings>

</telerik:RadAjaxManager>

The expected resulting error is:

Warning Generation of designer file failed: Telerik.Web.UI.AjaxSettingsCollection must have items of type 'Telerik.Web.UI.AjaxSetting'. 'telerik.web.ui.ajaxsetting' is of type 'System.Web.UI.HtmlControls.HtmlGenericControl'.

If I manually enter the markup, IntelliSense properly guides the creation of the tags to create the following:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxPanel1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

So what causes that?

I'm thinking this is just another variant on errors related to control references. With every release of RadControls and every new project I find myself frustrated with questions like the following:

Do I need a reference in web.config like this? :

<pages>

<controls>

<add tagPrefix="telerik" namespace="Telerik.Web.UI"
assembly="Telerik.Web.UI" />

</controls>

</pages>

Does that need to have the version ID?

Is it better to GAC for development or deployment?

Why is it that if I don't include a registration like the following in every user control I get errors on nested controls?

<%@ Register TagPrefix="telerik" 

             Assembly="Telerik.Web.UI, Version=2010.3.1215.35"

Namespace="Telerik.Web.UI" %>

And how do I avoid issues if I'm working on a client project that's a year old but my current system has the latest RadControls in the toolbox?

These kinds of questions and related problems have apparently affected the developer experience for many people over the years.

I'm hoping Telerik can publish a comprehensive new doc that describes the known issues and resolutions related to assembly references, page control references, nested user controls, master pages with RadAjaxManagerProxy, etc.

Thanks for your time.

[Solved] Adding Series to the chart X items

Hi, Im trying to programatically create a chart.

I hardcode Xaxis values of A, B, C and would like to add series coresponding to each of thsoe a b c values,

Unfortunately it always ends up adding all of the values to only one of the X axis items.

The fallowing code is the exert from my backend object

/radChartObj.PlotArea.XAxis.Items.Add(new ChartAxisItem("C"));

//radChartObj.PlotArea.XAxis.Items.Add(new ChartAxisItem("B"));

//radChartObj.PlotArea.XAxis.Items.Add(new ChartAxisItem("A"));

foreach (CallCenterStatistics callCenterStatObj in lstCallCenterStats)

{

chartSeriesObj =

new ChartSeries();

chartSeriesObj.Type =

ChartSeriesType.Bar;

chartSeriesObj.Name = lstChars[count] +

"-" + callCenterStatObj.Description;

chartSeriesObj.AddItem(

Convert.ToInt64(callCenterStatObj.Value), callCenterStatObj.Value + " - " + lstChars[count]);

chartSeriesObj.Items[0].Label.TextBlock.Appearance.TextProperties.Color =

Color.White;

chartSeriesObj.Items[0].Label.TextBlock.Appearance.TextProperties.Font =

new System.Drawing.Font("Arial", 8,FontStyle.Bold);

chartSeriesObj.Items[0].Label.TextBlock.Appearance.AutoTextWrap =

AutoTextWrap.True;

chartSeriesObj.Items[0].Label.Appearance.LabelLocation =

StyleSeriesItemLabel.ItemLabelLocation.Inside;

chartSeriesObj.Items[0].Label.Appearance.Position.AlignedPosition =

AlignedPositions.Left;

chartSeriesObj.Items[0].Appearance.FillStyle.MainColor =

Color.SeaGreen;

chartSeriesObj.Items[0].Appearance.FillStyle.FillType =

FillType.Solid;

count ++ ;

radChartObj.Series.Add(chartSeriesObj);

Any ideas what im doing wrong with this one?

Thanks!

Button Rendering Issue

    
            <asp:Button ID="btnHidden" runat="server" style="display:none;" EnableViewState="false" />

I'm not sure if this is a bug in the CSS inheritance of the latest browsers or a bug in the radFormDecorator. The button listed above displays on the screen, even though the inline style should take precedence over all other styles. I'm using a workaround of putting "display:none" in a CSS class which correctly hides the button (and prevents the radFormDecorator from rendering an anchor around the input element. I'm wondering if this is related to the "Opera hack" in the radFormDecorator's CSS file?

Customized Color picker tool item performance issue

We have added a color picker Tool Item using teh following configuration:

<tool name="ApplyBackColor" type="dropdown" ItemsPerRow="10" popupheight="120px">

<item name="<img src='./_wpresources/RadEditorSharePoint/5.4.1.0__1f131a624888eeed/Resources/ToolImages/colors/ffffff.png' alt='#'/>" value=""/>

<item name="<img src='./_wpresources/RadEditorSharePoint/5.4.1.0__1f131a624888eeed/Resources/ToolImages/colors/000000.png' alt='#000000'/>" value="#000000"/>

But the performance is extremely slow. there are around 50 colors that we want to display, and each color icon takes about .5 seconds to load.

Kindly suggest some better solution or performance improvement idea?

When binding Grid the Rate-event is fired a second time

Hello. I have broken down my problem into a very simple page and I'm sure the solution is simple as well. I do need to rebind the grid (not in this example but in my real scenario I do) and my question is why the Rate event is triggered a second time when rebinding the grid? I have already handled the Rate event, saved my rating to the database, and as a final step I want to rebind the grid so that some other data is updated, for example some average rating or something like that. (My grid template column is much more advanced in the real scenario with lots of controls that needs to be updated when a new rating has been saved).

I've played around alot with simple binding, advanced binding and all sorts of things but right now my example looks like below. Please tell me how to solve this.

Here is the Code Behind

public void Page_Load(object sender, System.EventArgs e)

{

if (!IsPostBack)

{

FillGrid();

}

public void FillGrid()

{

RadGridItemRateSimple.DataSource = new ItemRateDTOService().GetItemsBySearchCriterion(new ItemSearchCriterion());

}

protected void RadGridItemRate_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

FillGrid();

}

protected void RadGridItemRate_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)

{

ItemRateDTO itemRateDTO = (ItemRateDTO)e.Item.DataItem;

RadRating radRating = (RadRating)e.Item.FindControl("RadRatingItem");

if (radRating != null)

{

radRating.DbValue = CommonFunctions.SetDecimal(itemRateDTO.GetAvgRating());

}

protected void RadRatingItem_Rate(object sender, EventArgs e)

{

RadRating radRating = (RadRating)sender;

GridDataItem dataItem = (GridDataItem)radRating.Parent.Parent;

long itemID = CommonFunctions.SetLong(RadGridItemRateSimple.MasterTableView.DataKeyValues[dataItem.ItemIndex]["Item.ID"]);

Rating rating = new RatingService().GetSpecificRatingForUser(itemID, ActiveUserID);

if (rating == null)

rating = new Rating();

rating.ItemID = itemID;

rating.Rate = Convert.ToInt32(radRating.Value * 10);

rating.CreatedBy = ActiveUserID;

new RatingService().Save(rating);

RadGridItemRateSimple.Rebind();

}

and the aspx

<telerik:RadGrid ID="RadGridItemRateSimple" OnItemDataBound="RadGridItemRate_ItemDataBound" OnNeedDataSource="RadGridItemRate_NeedDataSource"

runat="server" Width="850px" AllowSorting="True" AllowPaging="true" PagerStyle-Position="TopAndBottom" PageSize="30"

AutoGenerateColumns="False" BorderWidth="0">

<MasterTableView DataKeyNames="Item.ID">

<Columns>

<telerik:GridTemplateColumn ItemStyle-VerticalAlign="Top" HeaderText="" SortExpression="ItemName">

<ItemTemplate>

<telerik:RadRating ID="RadRatingItem" runat="server" ItemCount="10" SelectionMode="Continuous"

Precision="Half" Orientation="Horizontal" AutoPostBack="true" OnRate="RadRatingItem_Rate" />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Thanks!
