Format strip noit working

None of the the stripping options allows me to clean the style tag from this paragraph:

<p style="color: #000000; margin: 0cm;">Wondzorg Nijmegen is een samenwerkingsverband tussen A-NIMO, het Canisius-Wilhelmina Ziekenhuis, ATC (Apothekers Thuiszorg Coördinatiecentrum), ZZG Zorggroep en NEO Huisartsenzorg.</p>

I have also tested in your demo environment.

How to achieve this?

Databinding keeps disappearing when post back

My page logic is that I click on an 'Apply' button, then in the Apply_Click method, I do some data binding, such as: Grid1.Datasource = xxx; Grid1.DataBind(); . And the grid can show properly on the page. But when I click on other buttons on this page (for example: click the filter on the grid) to trigger a post back, the content on the grid just disappears (The datasource is stored in a session, so it's not datasource's problem). I need to add databind() to Page_Load() to prevent this from happening. But this is very weird and feels not right. Can you help me locate the real problem?

The same issue is happening bothe in Grid and OrgChart.

How to change the node size of org chart?

I read this , but when I copied the code into my own project and followed the documentation, this just didn't work. The node size and the group size are weird. No matter how I tried to edit the css settings, the height of the node just wouldn't change. Can anybody help me?

And btw I also want to ask, what do .rocItem and .rocItemContent mean? When I use my browser's inspect function, I also see a .rocItemTemplate, what is that?

Unable to cast object of type 'Telerik.Web.UI.GridImageButton' to type 'Telerik.Web.UI.ElasticButton'

hi

I use radGrid with the following code:

         <telerik:RadGrid  
                ID="RadGrid_Fibers"  
                RenderMode="Auto"
                GridLines="Both" runat="server"
                Skin="Sunset"
                DataSourceID="SqlDataSource1_SP_Tow_Prog_Fibers_Select"
                AutoGenerateColumns="False">

                <MasterTableView Width="100%" ShowFooter="True"
                    DataSourceID="SqlDataSource1_SP_Tow_Prog_Fibers_Select"
                    DataKeyNames="TowProgFibers_ID">

                    <GroupByExpressions>
                        <telerik:GridGroupByExpression>
                            <SelectFields>
                                <telerik:GridGroupByField FieldAlias="Tow_Had" FieldName="Tow_Had" FormatString="" HeaderText="" />
                            </SelectFields>
                            <GroupByFields>
                                <telerik:GridGroupByField FieldAlias="Tow_Had" FieldName="Tow_Had" FormatString="" HeaderText="" />
                            </GroupByFields>
                        </telerik:GridGroupByExpression>
                    </GroupByExpressions>

that when a skin such as sunset is used, radGrid works without problems.

But when I don't want to use skin and Skin ="" is set with an error:

Unable to cast object of type 'Telerik.Web.UI.GridImageButton' to type 'Telerik.Web.UI.ElasticButton'

How to solve this problem? please help.

RadSpreadsheet format a range of cell as an Excel table

Does the functionality exist to format a range of cells as a table like can be done in Excel?

I use the data provider to read the format of an existing Excel file.

But, a range of cells formatted as a table is not copied into the RadSpreadsheet.

Uncaught Sys.WebForms.PageRequestManagerServerErrorException

I'm unclear as to what is causing this error but until recently this error was never being thrown.
Here's the details:
1. Clicking on a nav bar to load an .ascx page that's inside another .ascx page
2. Page never loads and appears to hang.
3. No server side errors are found during debugging so it appears to be client side

Here's the error message from Google Chrome's Developer Tools Console:

RadSpreadsheet Save Icon on toolbar

Is there a purpose of the Save Icon on the Home tab toolbar?

I would like to capture some kind of event when a user clicks this icon to direct it to my SaveWorkbook method override in my custom provider.

But, I don't see any such method implemented that can override.

If no ability exists to do this, why then is the icon even there?

Duplicate Group name in OrgChart

So I have a organization chart and a button. When I click on the button, I will fill in a DataTable stored in ViewState to be the data source of the org chart. Since I'm still having the problem in another post that nobody replied yet: Databinding keeps disappearing when post back in UI for ASP.NET AJAX | Telerik Forums So I add some handling in Page_Load to avoid the org chart from becoming blank.

My Page logic is as follows:

<Telerik:RadButton ID="btn1" OnClick="btn_click">
...
<Telerik:RadOrgChart ID="OrgChart1">

protected DataTable table1 
{
            get
            {
                if (ViewState["table1"] != null)
                    return (DataTable)ViewState["table1"];
                else
                    return  null;
            }
            set
            {
                ViewState["table1"] = value;
            }
}
protected DataTable table2
{
            get
            {
                if (ViewState["table2"] != null)
                    return (DataTable)ViewState["table2"];
                else  return  null;
            }
            set
            {
                ViewState["table2"] = value;
            }
}


protected void Page_Load(object sender, EventArgs e) 
{
       if (!PostBack) // do something
       if (table1 != null && table2!=null) {
                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldID = "aaa";
                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldParentID = "bbb";
                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataCollapsedField = "ccc";
                OrgChart1.RenderedFields.NodeFields.Add(new OrgChartRenderedField() { DataField = "A" });
                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataSource = table1;

                OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldNodeID = "aaa";
                OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldID = "ddd";
                OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataSource = table2;

                OrgChart1.DataBind();
       }
}


protected void btn_click(object sender, EventArgs e) {

               // do something to provide data for table1 and table2

                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldID = "aaa";
                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataFieldParentID = "bbb";
                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataCollapsedField = "ccc";
                OrgChart1.RenderedFields.NodeFields.Add(new OrgChartRenderedField() { DataField = "A" });
                OrgChart1.GroupEnabledBinding.NodeBindingSettings.DataSource = table1;

                OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldNodeID = "aaa";
                OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataFieldID = "ddd";
                OrgChart1.GroupEnabledBinding.GroupItemBindingSettings.DataSource = table2;

                OrgChart1.DataBind();

}

And then, when the page is post back, suddenly there are duplicate group names in the org chart as you can see in the screenshot.

Can somebody help me?
