Hello,

We are having a problem with the grid not maintaining column width on postback when you set EnableViewState = false. If I enable the property it works. However, there are other problems that occur if we leave it enabled.

We were running on the last 2012 build up until now. I noticed in the 2013.1.220 release notes this: "Fixed:EnableViewState property of RadGrid does not turn off the ViewState of RadGrid instance”. And according to this documentation http://www.telerik.com/help/aspnet-ajax/grid-viewstate-optimization.html, various column properties are maintained even with the property set to false.

To recreate the problem all you need to do is create a declarative grid and set EnableViewState=false and hookup the onColumnResize event to postback. 

Also, if you reorder columns first and then resize a column, the order will reset.

Any help would be appreciated.

I have a DatePicker in a RadGrid defined as follows:

I cannot seem to get the calendar to popup on clicking the date box. The problem is I can't seem to find the ClientID of the DatePicker. Using <%= dp_scout_dob.ClientID %> either in a $find command in the JavaScript or passing it in the onclick event both return NULL. I even tried to figure out the actual elementID and use a getElementByID command in the JavaScript, but I couldn't seem to figure out what the actual ClientID is.

Can someone point me in the right direction? Either help me figure out how to reference the ClientID or what the actual full ClientID is if this control is inside a RadGrid? Thanks.

Hello,

I'm currently working on a project with RadGrid.

In my grid I have the first column GridClientSelectColumn (Checkbox).

VB.NET Code:


When I click "Select all", all the rows on the same page are selected.

What I need is that when I clicked "Select All / Select None" it will "Select / Un-select"
all rows in all pages.


Thanks in advance,

Daniel.

Hi,

Could you show me how to get the innertext (company_name) from the legend in the ItemCommand event?  I tried the following, but the error is object reference not set.

Here's the partial code that shows the legend:

Here's the code-behind


Thank you,

Helen

I want to create a barchart as displayed in the figure. Not able to create an additional X axis in the RADHTMLChart. Please guide me how to create a bar chart like this.

Hi ,
I have binded a RadHtmlchart where my Datatable contains mixed numbers like few may be numbers and few are decimals so, when I see the tootltip I see in number format though conditionally I am assigning the tootltip as {0:N} for decimal and {0:N0} for number so,please let me know how solve this as when decimal data is there in tooltip expected is a decimal ex:22.44 and for number ex:22 is expected.

Thanks,
Chary.

I'm programmatically binding data to a RadSearchBox [I get my data list back from a Service Reference] and I set the DataTextField and DataValueField, then I set the DataSource - all without errors.  However, when I start typing in the search box, I receive a popup on the page: DataSource not set

What am I missing?

A normal asp:Panel with GroupingText set should render as a fieldset with GroupingText's value as its legend. This code below works.


But the same code using the RadAjaxPanel does not.

I have a radgrid with search functionality,when i search a record and press tab the cursor gets lost,ideally it should go to next filter column.This is happening only in core IE8.I have attached gif file for more details.Please have a look.



Please Suggest.
