Hi all,

Is there anyone with a simple sample for string concatenating in a databinding field...

Here's my case.
I have a RadGrid with a hyperlink column. I want the link to link to a customer, but also to add a querystring parameter called returnurl.
The value of the ReturnUrl is the AbsoluteUri of the page. It can vary by it's QueryString.
A simple thing in many ways. And I could solve this by using the databound events, but I just think that another solution must be possible.

This is one take I tried. ReturnUrl is a public property on the page, returning the AbsoluteUri of the page. I did remember to call DataBind on the page.

    
            <telerik:GridHyperLinkColumn DataTextField="Name" HeaderText="Name"   
        
            UniqueName="ClientName" DataNavigateUrlFields="ID"   
        
            DataNavigateUrlFormatString="clEdit.aspx?clID={0}&amp;returnurl=<%# ReturnUrl   
        
            %>" >

I also tried to make the call directly to the Request.Url.AbsoluteUri in stead of the property.
I also tried with ' in stead of "

So, if anyone has a take on this, please help me :)

Kind regards,
Morten

Chart with lots of values and large legend?

Hi

I'm trying to plot a chart that has about 35 columns (bars) and for each the legend needs to display about 100 - 200 characters of text.

I've tried moving the legend below the chart which works but it all seems to overlap and look very confused.

Does anyone have any tips on this?

Code I'm using@

rc.Legend.Visible = true;

rc.Legend.Appearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Bottom;

rc.Legend.Appearance.Location = Telerik.Charting.Styles.LabelLocation.OutsidePlotArea;

rc.PlotArea.Appearance.Dimensions.Height = 500;

rc.Legend.Appearance.Dimensions.Height = 2000;

Thanks in advance

GridDateTimeColumn filter boxes too tall

screenshot

I have dynamic filtering set on my grid, so users can turn it on or off.
In IE8 upon first rendering with filters off they look normal, but will hide automatically.

However when calling the rebind, all the date filters double in size.

I cookie the filter choice so it carries over to the next grids they view.

here is my javascript code. i sure wish there was a server side event for this that would happen in Ajax !

    
             <script type="text/javascript">  
        
                            function pageLoad(sender, eventArgs) {  
        
                                var filter = getCookie("filter");  
        
                                if (filter != "on")  
        
                                    $find('<%=rgSO.ClientID %>').get_masterTableView().hideFilterItem();  
        
                                    $find('<%=rgSO.ClientID %>').get_masterTableView().rebind();  
        
                            }  
        
                            function showFilterItem() {  
        
                                var masterTable = $find("<%= rgSO.ClientID %>").get_masterTableView();  
        
                                masterTable.showFilterItem();  
        
                                masterTable.rebind();  
        
                                setCookie("filter", "on", 7);  
        
                            }  
        
                            function hideFilterItem() {  
        
                                var masterTable = $find("<%= rgSO.ClientID %>").get_masterTableView();  
        
                                masterTable.hideFilterItem();  
        
                                masterTable.rebind();  
        
                                setCookie("filter", "off", 7);  
        
                            }   
        
                        </script>

Elements replaced instead added

Hi,

I put an "Insert Groupbox" item in the toolbar and I wrote a function for it like this:

    
                  <script type="text/javascript">  
        
                    Telerik.Web.UI.Editor.CommandList["InsertGroupbox"] = function(commandName, editor, args) {  
        
                      var selElem = editor.getSelection().getParentElement();  
        
                      if (selElem.tagName != "FIELDSET") {  
        
                        editor.pasteHtml('<fieldset style="left: 20px; top: 20px; width: 200px; position: absolute; height: 80px;">Place your text here... </fieldset>');  
        
                      }  
        
                    };  
        
                  </script>

It's working nice while the cursor is in the body text of the editor.
But when an existing Element is selected (groupbox, image, etc.), the element is removed and the groupbox is inserted.

How to create an exception to avoid this replacement only when inserting groupboxes ?

Thanks,
Sébastien

[Solved] Displaying an empty list with an insert item template

I have a photo gallery page where the initial state is there is no photos. I am trying to figure out how to show the insert item template view by default rather than the EmptyDataTemplate. When I set InsertItemPosition in the NeedDataSource event it appears to have no effect except when I set the EmptyDataTemplate to null. Seems like a hack to me?

Any thoughts on why this isn't working?

Thanks,
Colin

[Solved] Basic filtering with LLBLGenProDataSource2 control

I'm running into an issue with filtering the grid that is bound to LLBLGenProDataSource2 control. Everything appears to work fine (selecting, paging, sorting). However, when I try to use filtering with AllowFilteringByColumn=true, I'm running into a problem where the grid appears to not recognize the objects it is bound to. Below is the stack trace. The final error refers to EntityBase2 class, which is the LLBLGenPro base class for the actual derived entities. The base class of course doesn't have the properties such as AcctCode - these properties are on the derived class. I'm using the 2009.3.1103.35 release.
