Hello,

How and where to specify/have/assign telerik:GridDropDownColumn on specified column when we have AutoGeneratedColum=True on RadGrid ?

Thant mean having specific colum as telerik:GridDropDownColumn when AutoGeneratedColum=True.

Thank you
Regards
Ganapathy

I have a date that I pull into my radgrid that I need to then convert to datefield so that I can color code them but whatever i do it never seems to work.  how can I change this string to date.

I need an example of the following.

• A RadGrid bound via its OnNeedDataSource event. The grid should also have an Edit Template. 
• The source of data should include at least two fields, LookupId and LookupValue.  Of these two, only LookupValue should be visible when NOT editing.
• When editing or inserting, the edit template should contain a DropDownList or RadComboBox bound to a Lookup Table of IDs and Values.  Best would be if that source were an ObjectDataSource since that's what I'm using, but not sure that's required.

i tried numerous ways but still not able to get the paging work correctly. I am using JSON to bind the radgrid client side. Everything works  well except paging.

Please let me know how can I get the paging work with JSOn method. I dont want to do it with Getdate() and Getcount() methods

Attached is my code

Hi,

I got a RadTextBox and after user enter some value and move to the next textbox, I want to check if the value is greater than 18. And if the condition fails, display an alert and clear text.

Thanks,
Karl.

Hi guys

I looked some posts in regards to Radar Chart back in July 2009 and back then Telerik has no plan to make this as apart of RadChart. Now it's 2010 so I am just wondering if this is still the case.

I am appreciated your feedback.

Thanks

Hello,

I am trying to get the background/background color of the RAD HTML 5 Column Chart to be transparent but no matter what I do it is always white, unless, of course, I set it to some other color besides white (e.g. green).

I want to lay the chart on a larger background image but the charts plot background is always white.

How can  I make the chart transparent so I can see the background image underneath it?

The following grid opens an Edit Template instead of firing the OnInitInsert event when I click LinkButton2, and I can't figure out why.

Hi

I'm using telerik.web.ui version 2013.1.220.35 and was wondering if the following is a known bug.
On a radgrid when I apply an "ItemStyle-VerticalAlign" property in the MasterTableView, instead of in the individual columns, then (at least for) the GridEditCommandColumn and GridDropDownColumn, the style gets applied to every alternate row only.

For the skeletal mark up listed below, notice that the MasterTableView defines ItemStyle-VerticalAlign="Top".
See attached screenshot for this markup. you will see that the Edit Image and the text in the "Type"  column is "Top" aligned only on alternate rows. To make these values Top aligned on every row, I need to specify the ItemStyle-VerticalAlign on each column.

So I was wondering if 
a - This is a known issue with specifying  ItemStyle-VerticalAlign in the MasterTableView
b - There is a way so that I can specify this value in a single place on the radgrid so that it correctly applies to all columns.



Thanks

I have two grids on the page. Both are configured to use the OnNeedDataSource event. The detail grid is rebound in the OnSelectedIndexChange of the master grid.  The detail grid has an edit template with a dropdownlist.  The dropdown list is bound to an ObjectDataSource.  I'm attempting to bind the dropdownlist in the following event handler;


However, before it can get here, I get an error: "Sys.WebForms.PageRequestManagerServerErrorException: 'ddlAssetType' has a SelectedValue which is invalid because it does not exist in the list of items."

The code doesn't hit a breakpoint set in the OnSelect method of the ObjectDataSource, so the dropdownlist hasn't been bound yet. What am I doing wrong?
