Hello All,

I have a RadGrid with EditCommand Column as the first column in the grid. I have a edit image set for all the rows in that column. I did this by putting the editImageURL property.
Now. My question is, Is there a way to change the Image of that column dynamically based on the value of other column in the grid?

I want to change the first column's image of a grid based on other column value. Can i do it in the aspx page or Is it best way to do it from code behind?

If I have to do it from Code behind, How can I access the image folder( which has all the images I am using in the project) in my project from code behind. If it is aspx page we can set the property like editImageUrl .

Sys.WebForms.PageRequestManagerServerErrorException

On one of my pages I'm getting this error when I click on the calender control on my page...

Error: [Exception... "'Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

It doesn't give the error when I run from VS 2008 but when I promote to any other server I get the error. It only happens when I click on the calender control.

I searched these forums (and others) and have tried all of the suggestions (there are no response.writes, response.transfers, or anything like that).

Excel exporting

Hi. I was wondering how I could export data that's been rendered in a Treelist, into an Excel file, maybe not with the methods included with control, but some other class which I could use.

Could anyone help me?
Thanks in advance.

Multiple RadColorPickers consuming too much memory

I am using the RadColorPicker in an asp.net repeater control.

Everything works well except that the browser (any browser) is consuming approximately 500MB of memory 

with only 13 items loaded into the repeater.

If I comment out the radcolorpicker, memory consumption drops to around 60-70MB...  which is a little 

more appropriate.



Memory usage is the same regardless of whether or not I handle the OnClientColorChange event, so I'm 

pretty sure that whatever is going in is happening as a part the control's default behavior.  



I am using the latest available controls.



Are there any known issues with this control and memory leaks/consumption?



Thanks...

How to enter line breaks in RadGrid

Hello,

I am using RadGrid from RadControls for ASP.NET v2008.1.619 to display and edit TEXT fields from a Microsoft SQL Server database.

I am trying to insert line breaks in the text using an ASP.NET TextBox (multi-line) in an EditFormTemplate. When I press Enter the line break works as expected. When I update the RadGrid the text in the RadGrid is not honoring the line break. I also tried using Shift-Enter which works in the ASP.NET TextBox but when displayed back in the Grid after updating does not work. I tried using <br> tags but they just render in grid as <br> and do not break the line.

Is there a way to enter line breaks and have them work in the RadGrid?

Thanks,

Randall Price

Custom Attributes on a RadTreeNode checkbox

I've been searching around and I can't find anything pointing me in the right direction to do this. I need to add a custom attribute to each checkbox associated with a RadTreeNode inside of a RadTreeView. Not every node is checkable, but for the ones that are I need to figure out a way to add a custom attribute to those checkboxes. Does anyone have any suggestions?

Let me know if you need more info to help me out.

show alert for errors in RadGrid ItemCommand

Hi,

I am using radgrid for a long time now. Earlier I simply use to throw exceptions which occurred in RadGrid ItemCommand or InsertCommand or UpdateCommand and they use to appear as alerts in IE.

I don't know whether it was IE version update or rad grid version update or did I missed some property of RadGrid because of which instead of alerts all my validations are appearing as IE errors.

I just wish to catch exceptions inside RadGrid ItemCommand or InsertCommand or UpdateCommand and show them as alerts. Please help me out with this.

Thanks
