I've got a grid that I need to sort by a column that refers to a related entity. I need to figure out the syntax to do this.

 

Details:

The above throws an argument exception: Input string was not in a correct format.Couldn't store in PAgents.AGNAME Column. Expected type is Int32.

The grid is bound to an entity data source (defined below)

The two relevant data sources:

 

 

 

I am having a problem with grouping on a grid. I have two select fields, one which shows the current group, and one which shows a count of rows.

The header text works fine on the first group, but all subsequent groups, it looks like it is just showing a template of the text.

The attached image shows the way it is coming out. I collapsed the first group so all the group headers could be seen together.

You can see that the first group shows up fine showing "Pass: ; Fields: 73". This is correct, as that first group, all of the rows have the value for the PASS field empty.

But then the subsequent two groups are wrong. Taking the second group as example, it SHOULD show "Pass: 6; Fields 1", but instead it shows "  Fields: {0}".

The below is the code for the groupbyexpressions for the grid in question.

I'm having problems finding a control in my grid.  I've been stuck on this for a couple of days and have searched the forums, following examples and links to documentation, with no luck.  Here's a snippet from the aspx page.


And here's a snippet from code behind.

DropDownList list =item.FindControl("HeaderDropDown") as DropDownList;  always returns null.

What am I not getting here?

Thanks,

I've seen a ton of questions on this, however no simple explanations why this is occurring or what the solution to the problem is.

We've got a Batch Edit Update Grid that I originally had a RadComboBox in that was working fine until I found that keyboard navigation was screwing up the keyboard flow and saw that it was recommended to switch to a RadDropDown control, so I did, which is in a GridTemplateColumn similar to this:

 

In the examples and the problems/posts that I have seen, they all recommend checking the e.item type in the ItemDataBound event.  If the e.item is a GridDataItem then bind a label, else if it's a GridEditableItem bind the dropdown, IE:

 

Problem is, this code never gets called:

 

I'm pulling my hair out on this one..

 

 

Given the following object structure...

    public class CategoryViewModel
    {
            public int category_id {get; set;}

            public string category_name {get; set;}
            public List<CategoryDetailsViewModel> details { get; set; }
    }

    public class CategoryDetailsViewModel
    {
        public string category_detail_id {get; set;}

        public string category_admin {get; set;}
    }

 

Is it possible to use a DetailTable where the details are defined in the parent object? For example, I've tried this, though all the detail tables were empty:

    <telerik:RadGrid runat="server" ID="rgCategories" OnNeedDataSource="rgCategories_NeedDataSource" Skin="Silk" AutoGenerateColumns="false">
        <MasterTableView>
            <DetailTables>
                <telerik:GridTableView Name="Category Details">
                    <Columns>
                        <telerik:GridBoundColumn HeaderText="Category Admin" DataTextField="details.category_admin"></telerik:GridBoundColumn>
                    </Columns>
                </telerik:GridTableView>
            </DetailTables>
            <Columns>
                <telerik:GridBoundColumn HeaderText="Category" DataField="category_name"></telerik:GridBoundColumn>
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

I have been trying to create a custom sort on a grid on my front end application and the compare function is never called.  I tried running the sample code here to see if I had missed something but that doesn't work either.  Can anyone offer a solution please?  I have tried this in IE11 and the latest version of Chrome with the same result.

I have this RadComboBox (ddlSrvTypCde) that triggers the radajaxmanager but I don't want the controls on the last <tr></tr> to get affected. I tried putting PostBackControls but it doesn't work.

            centerElementOnScreen($get("<%= AjaxLoadingPanel.ClientID %>"));
        }

I am writing a page that uses a RadEditor for an administrator to create text files.  The other users need to read these files.  Is there a Telerik control that displays rich text or should I make the RadEditor readonly and hide the RadButton? 

 

 Does anyone know of a way to easily prevent double clicking the next button. e.g. I dont want to charge the user's credit card twice.

 

Any help would be great. Thanks!

I have a situation where users need to edit previously entered data, which might not be valid.  For example, assume the valid range for an invoice date is the current month (10/1/2017 to 10/31/2017).  Also assume I have an existing invoice with a date outside that range (11/5/2017).  I'd like to present the invalid value to the user, and have the min/max validation force them to fix it. 

Ideally, I could just set the min, max, and selected values in the code behind, and let the client side validation do it's job.  However, setting the selected date to the invalid date in the code behind throws an exception.  I also tried setting the selected date first, then applying the min/max...but then it changes the selected date based on the min/max.  And the InvalidTextBoxValue is read only, so that's not an option.

 

Is there a way to have the initial date value be an invalid value?  I used the example of a date being outside the min/max range...but in our situation it's possible that the original value wouldn't even be a valid date.  Is there anything built into the control that would help with this situation?  One option would be to not use the built in min/max...and implement my own client side validation to do the range check.  But I view that as a last resort.
