I am getting the Error "No property or field 'rEqualTo' exists in type 'DataRowView'"

I am getting the error No property or field 'rEqualTo' exists in type 'DataRowView' when I try and choose either the "GreaterThanOrEqualTo" or the "LessThanOrEqualTo" option in the dropdown.

When I debug my code the FilterExpression looks like be what is below

MainGrid.MasterTableView.FilterExpression = ["TOTAL_AMOUNT_CREDIT"])) > rEqualTo|234

Also the CurrentFilterFunction and the CurrentFilterValue have changed from what I enter.

MainGrid.MasterTableView.Columns[2].CurrentFilterFunction = GridKnownFunction.GreaterThan

MainGrid.MasterTableView.Columns[2].CurrentFilterValue = rEqualTo|234

Product version 2021.2.616.45 for the below DLLs.

Telerik.Web.UI.Skins.dll

Telerik.Web.UI.dll

Telerik.Web.Device.Detection.dll

Telerik.Web.Design.dll

Where I use version 2021.2.511.40 of the DLLs everything works fine and the

MainGrid.MasterTableView.FilterExpression = ["TOTAL_AMOUNT_CREDIT"])) >= 234

Is there something I am doing wrong with version 2021.2.616.45 of the below DLLs.

Thanks,

Kevin

RadEditor Is there a tool option to sort a table by alphabetical order in the editor view?

Is there a tool group available to sort a table in alphabetical order that has been entered into the editor with the insert table feature? If not, is there an easy way to incorporate this?

[Solved] RadMap and US Counties

I have RadMap opening in a WebForms application using Bing tile services. It works. What I'm trying to do is color code counties based on data values. How would I go about doing something like that?

[Solved] Apply style to some but not all.

I have a page with a few Comboboxes. Not all of them are required, but the ones that are I would like to make the back ground color yellow. I see that there is a property for BackColor and InputCssClass. That all well and good, but the input area is rendered within a <span class="rcbInner">. If I only change the BackColor and InputCssClass to be yellow the <span> around it is still white. So what I would like to to do is change the rcbInner only for certain controls. I have a radcombobox named cbCC_Month so I thought this might work:

        #cbCC_Month rcbInner {
            background-color: yellow !important;
        }

It did not.

Bootstrap grid builder integration

This is more like a feature request...very powerfull addition would be a Bootstrap grid builder like this one:

https://www.youtube.com/watch?v=WQZ9zcf_ZRo

How cool would that be, building your Bootstrap parts in the Editor itself. Did anyone try this? Any hints on how one could build this functionality.

Please let me know if we could collaborate to get something like this.

telerik:RadScheduler -- Exception: 13.333333015441895 is not a valid value for Int32

Hi, This is little bit weird and hard to debug. only one user (rest of the 10 business users are not having this issue on their computers, and all users are having similar systems and applications and all are using latest chrome browser only) is getting below error when trying to open advanceedittemplate in telerik:RadScheduler by clicking on any event on the calendar control. we are using 2012 version telerik.web.UI.dll.

tried to put try catch block in all the events but it logs below error only. and more over I'm not able to replicate this issue on the development machine using Visual Studio 2012.

Get Mouse Coordinates while drawing/cropping

Hi,

I am able to get the mouse position using the client sides events but is it possible to get the starting/ending mouse positions while drawing a rectangle? or is the information from the cropping window available on the client side (Width, Height, Position X,Y?

The requirement is to have the user identify something on the image and create "tag". Ideally, the user can use the rectangle to draw the outline. I would need to get the starting/ending mouse coordinates.

I can use the click events but that is not ideal.

I tried to use some other client side events but with no luck.

Thanks.
