Hello,
I have a RadListBox called RadListBoxDestination inside the controls <EditFormSettings EditFormType="Template">
<FormTemplate> (file wucMantenedorVentasPriorizadas.ascx)
What happens is that when I try to call RadListBoxDestination ma I get the following error message:
"Object reference not set to an instance of an object"
For me the problem is that my RadLisBox called RadListBoxDestination is inside the controls <EditFormSettings EditFormType="Template">
<FormTemplate> and I'm not calling it correctly.
For this I have been doing 2 possible logics but I get the same error, these logics are (file wucMantenedorVentasPriorizadas,ascx.cs):
Option 1
logger.Info("RadListBoxDestination: " + RadListBoxDestination);
RadListBoxDestination.DataSource = AGAgents.Select(a => a.firstname + " " + a.lastname);
RadListBoxDestination.DataBind();
Option 2
if (e.Item is GridEditFormItem && e.Item.IsInEditMode)//editform
{
GridEditFormItem editItem = (GridEditFormItem)e.Item;
RadListBox RadListBoxDestination = (RadListBox)editItem.FindControl("RadListBoxDestination");
RadListBoxDestination.DataSource = AGAgents.Select(a => a.firstname + " " + a.lastname);
RadListBoxDestination.DataBind();
}
Can you help me how is that How do I reference it so that the data can be loaded dynamically since I put a log to see but no data appears in the RadListBox
Regards
Oscar

Hi,
Nowadays which is the best method to change the default Crop sizes of the ImageEditor? I can see you are using a telerik:RadComboBox for the control so don't understand why there isn't a easy way of populating it with other values.
Thank you!

Hi,
I cannot seem to add a RadFilter control to my aspx page or user control.
It keeps showing "RadFilter is not a known element".
The telerik assembly was registered at the top of the page and also in the web.config but still I can't get it to work.
Am I missing something here or what?
Thanks for you help.

How can I create a custom shape (polygon) using Json object with coordinates after OnClick event in Javascript?
I've tried the following but I'm getting an error: Uncaught TypeError: a3.slice is not a function
function initialize(sender, eventArgs) {{
var shapeData = {{
""type"": ""GeometryCollection"",
""geometries"": [
{{
""type"": ""LineString"",
""coordinates"": [
[
12.47633,
41.9106979
],

}}
]
}};
var originalOptions = eventArgs.get_options();
originalOptions.layers[1].dataSource = {{ data: shapeData }};
eventArgs.set_options(originalOptions);

I have a oracle procedure that returns the following data from a user search
First column is a checkbox
ckbx Label Name Year Category Type
Label1 Name1 2020 Cat1 Type1
Label2 Name2 2020 Cat1 Type1
Label3 Name3 2021 Cat2 Type1
Label4 Name4 2022 Cat3 Type2
Label5 Name5 2021 Cat4 Type3
Label6 Name6 2021 Cat4 Type3
Hierarchical display (Type, Category, Year, Label, Name)
Type1
|_Cat1
|_2020
|_ckbx Label1 Name1
|_ckbx Label2 Name2
|_Cat2
|_2021
|_ckbx Label3 Name3
Type2
|_Cat3
|_2022
|_ckbx Label4 Name4
Type3
|_Cat4
|_2021
|_ckbx Label5 Name5
|_ckbx Label6 Name6
This will allow the user to click only the type they want to see values returned then be able to check the box and add to their cart the data they want to download.
I'm using VS 2019 professional, C#, and Oracle DB 19c, telerik tools are from 2020_1_114_dev_hotfix for asp.net
thank you

Hello,
i worked on radgrid with batch edit commands : Add, Save and Cancel.
It works fine with inherited buttons, but when i try to have CommandItemTemplate buttons, it doesn't work for the add button.
When i click on the add button, i t's calling this function :
grid.get_batchEditingManager().addNewRecord(grid.get_masterTableView());
An added line, empty, is shown in radgrid, it's ok.
But then, i click on the save button, to save the data added, and it's calling this function :
grid.get_batchEditingManager().saveChanges(grid.get_masterTableView());
The problem is that in my server code, in BatchEditCommand(sender As Object, e As Telerik.Web.UI.GridBatchEditingEventArgs), command.NewValues is null and also command.type is UPDATE and not INSERT.
In spy mode, i saw the data i want to add in command.Arguments, but i cannot access them.
What am i doing wrong ?
Thanks in advance.

Hi there;
I have a grid bound to a datasource, and the grid is set to dynamically generate columns at runtime (i.e. show whatever the data source returns). I need to change the caption on some of those columns, however. I tried access grid.MasterTableView.Columns in both grid_Databound and Page_PreRender, but it's empty in all cases. What am I missing?
Thanks,
Jason
