How do I use RadDatePicker inside a Custom Server Control using HttpTextWriter? It seems that the Telerik control hates the invocation of `RenderControl` outside of a UI.Page class. Its a shame as the standard .Net controls honor `RenderControl(writer)` perfectly - yet Telerik controls don't. I assume this has to do with the script manager and registering events.

How can I get the flexibility of custom server controls whilst still being able to place Telerik controls inside them. User controls are not the answer.

Any suggestions or implementations?

Thankyou.

Hello,

I am using a custom data object with a select-method that collects data from different tables, adding data from cached object collections etc. This is done with linq. It's working great with one exception: filtering data. When filtering data I cant get the filtering expression in a linq-syntax.

My radgrid has EnableLinqExpressions set to true, and my ObjectDataSource looks like below:



I set the parameters in the selecting-event of the ObjectDataSource:


How can I get the filterexpression to be in a linq-friendly format so that I can use it in my linq-query?

If you click on a dropdown in the iphone or ipad you get the keyboard popup, even though it is only a dropdown. There is no way to turn that off.

Already I implemented custom sorting and custom paging with objectdatasource and database. Now I need to implement custom filtering in rad grid with objectdatasource and database.

Can you send me any sample solution?

Hi Team,

While we are using Telerik control functionality we are facing following issues. this is very serious and waste of our time also, Please check the following issue and let me know if already fixed.

Currently i am using Telerik Version 2013.3.1324.40

1.RadMenu

I am using RadMenu binding with LoadXml. i want to use EnableRootItemScroll="true". in that time i move the mouse continuously i got the alignment issue. please check the attached screen shot. if EnableRootItemScroll="false" it is working fine. but i want to use EnableRootItemScroll="true".
in this issue we can not tell users do not scroll more then one time. please check and let us know ASAP.

2.RadGrid Filter Case Sensitive using EntityDataSource

Case Sensitive is not working using EntityDataSource. but it is working in sqlDataSource. in this case we can not tell users case sensitive is not working. please check the attached Screen shot and let us know ASAP.

Hi all,

Currently I am facing a problem regarding Radgrid Group Footer Dynamic calculation.

I have a radgrid that have some GridTemplateColumns that allow me to key in some value

Example

 <telerik:GridTemplateColumn UniqueName="Quantity" HeaderText="Quantity"  DataField="Quantity" Aggregate="Sum" >
                                        
                                            <ItemTemplate>
                                                 <asp:TextBox ID="lbl_Quantity" Text='<%# DataBinder.Eval(Container.DataItem, "Quantity" , "{0:0.00}") %>'
                                                    Width="40px" runat="server" autopostback="true" onTextChanged="calQuantity"></asp:TextBox>
                                                <br />
                                            </ItemTemplate>
                                        </telerik:GridTemplateColumn>

 

 <GroupByExpressions>
                    <telerik:GridGroupByExpression>
                        <GroupByFields>
                            <telerik:GridGroupByField FieldName="Grp"></telerik:GridGroupByField>
                        </GroupByFields>
                        <SelectFields>
                            <telerik:GridGroupByField FieldName="Grp" HeaderText="Week"></telerik:GridGroupByField>
                        </SelectFields>
                    </telerik:GridGroupByExpression>

 

Group Footer displayed correctly when the grid load. However, what I was trying to achieve is when I change the value of the quantity it will auto recalculate the group footer. I tried to achieve it using onTextChanged="calQuantity" but not success.

Do you all have any idea on this? 

Thank you.

hi

is there any skin/easy way of implementing the tab strip in vertical mode , but having the text vertical too ?

 

Peter

Can I use RadAutoCompleteBox for completing the text I write (not selecting single or multiple items) and bind just the text property in design time?

 

Hi.
I am porting an old applications chart section from RadChart to RadHtml chart and am struggeling with how to edit serie items prior to rendering. The main problem is that since we are binding against an list of objects where some integer properties contains -1 values (which in our context means NULL/UNDEFINED). I cannot change this behaviour of the object since the system heavily rely on that fact.

When using RadChart we could "hook into" the series items in the ItemDataBound event. See example below.

How can I achieve the same thing with RadHtmlChart ?
