Hi,

I m using telerik grid with grouped by month.

now my criteria is i want to show current month group first  and then remaining group with order by asc .

Is there any way to accomplish this?.

Thanks in advance.

I'm getting the following error when trying to use a radcombobox inside GridTemplateColumn with inplace editing (i.e. using bind to SelectedValue).

Error:
Cannot insert the value NULL into column 'GroupTitle', table 'cms_XXXXX.dbo.cmsContentRelatedGroup'; column does not allow nulls. INSERT fails.

Why would the control pass a null value when the user enters a new "custom text" item?  Any help would be most appreciated.


Below is my RadGrid:

Hi,

My team is having an issue with the NumericTextBox and the developer currently having the issue asked that I post his question in the forum on his behalf since he is having a technical issue with his workstation that is preventing him from posting himself.

"Using the NumericTextbox, I am seeing behavior that is not the way that I want or expect. I have a MinValue="0" and a MaxValue="100". I have a InvalidStyleDuration="2000000".

When the user enters -1, the textbox border turns red and there is an invalid icon in the textbox. What is happening that I don't want is that the -1 value that was entered is replaced by the MinValue, 0. How can I get the entered value, -1, to remain in the textbox?"

Thanks,

Andrew

Hi,

My team is having an issue with the NumericTextBox and the developer currently having the issue asked that I post his question in the forum on his behalf since he is having a technical issue with his workstation that is preventing him from posting himself.

"I have a NumericTextBox that has MinValue and MaxValue properties.I have a ValidationSummary control which has a RequiredFieldValidator connected to another asp.net TextBox control.

When the user hits the Save button and validation takes place, is there a way for invalid values in the NumericTextBox control, for example value entered is less than the MinValue, to be displayed in the ValidationSummary control without hooking up an additional asp.net validation control?"

Thanks,

Andrew

Hello,

I've been looking around the Telerik and the internet for the last few days to fry and find a possible solution for designing a grid that allows manual entry.  To be specific, here's exactly what I am looking for -

1. User clicks Add New Record to enter new data
2. Mouse cursor automatically starts in the first data field; as the user tabs across, the cursor continues to move from column to column, allowing the user to enter all values
3. The input of each field can be customized - in other words, some of the entry fields would simply be text entry, some would be dropdown menus (RadCombo) and some are date fields (RadDatePicker)
4. When the user tabs from the last column, the record is automatically validated and/or inserted into the grid.  The cursor then returns to the first column to allow entry of the next record

I have been experimenting both with the User Control and Template Edit Form Type (currently I am working with the Template).  There have been a few issues based on how I'm coding it:

1. Despite setting the tab index of the items in the template, tabbing through them is giving a random tab order and not following the set tab index settings
2. I am curently working with the last field in the template set with Auto Postback - this was my initial plan for simulating the automatic insertion, although I was doubtful this would work (and so far it hasn't).

Is there a sample somewhere on the Telerik site that follows a similar approach?  I haven't been able to find anything that mimics this behavior, but perhaps I am searching for the wrong thing or describing it wrong.

Hi,
I have many columns in my radgrid, and thus I have horizontle scrolling enabled. But, I would like to allow the user to select the columns they want to have displayed by having option on the header of a column as shown in the below link:
http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextfiltermenu/defaultcs.aspx

Eveything is good, but my radgrid columns are created programatically. It would be great if someone can guide me in doing this programatically in code behind file.

Thanks,
Raj

In the above example, even though the second file Lighthouse.jpg fails validation, it in the file list. Although the green and red bullet show the status of each file, it is not as intuitive, especially if you select multiple at a time. Firstly you have to scan through the list to see which all failed. Secondly colourblind people can have a hard time distinguishing them.

How can I make it so that files that fail validation don't show up there? I'm planning to have a error area below the upload control that will list files that fail validation and only show validated files up there.

Thanks.
