The reading path image displays an error, the program code is as follows:
private void button1_Click(object sender, EventArgs e)

OpenFileDialog _file = new OpenFileDialog();
_file.InitialDirectory = ".";
_file.Filter = "JPG(*.JPG;*.JPEG);|";

Thanks,
Jeen

I am trying to figure out if updating different packages in my project is possible and would like to find the documentation for my Telerik version. I have a old version and can't find relevant information anywhere.
Is there some legacy page i can view?

Hi Dinko and Team,
As I mentioned in my previous forum, The below code is working in VS 2022 with 2013.3.1.1127 where as throwing stackoverflow exception in VS 2022 with Telerk 2024.1.130.48. Out product code structure is like below and we cannot declare and initialize the datatable globally. If we did that the whole application will get impact . Hence could you please restrict the recursive call of Raddropdownlist.Datasource and Raddropdownlist.SelectedIndex also like Raddropdownlist.SelectedValue. Which I raised in my previous forum
public void fillIndustryProcess()
{
try
{
System.Data.DataTable dt1 = new System.Data.DataTable();
if (dt1.Columns.Count <= 0)
{
dt1.Columns.Add("Industry", typeof(string));
dt1.Columns.Add("ID", typeof(int));
dt1.Rows.Add("USA-0", 0);
dt1.Rows.Add("USA-1", 1);
dt1.Rows.Add("USA-2", 2);
dt1.Rows.Add("USA-3", 3);
dt1.Rows.Add("USA-4", 4);
radDropDownList2.DisplayMember = "Industry";
radDropDownList2.ValueMember = "ID";
}
radDropDownList2.DataSource = dt1; ;//Still stack overflow exception occurring when bind the radDropDownList
radDropDownList2.SelectedIndex = 0;
}
catch (System.ComponentModel.Win32Exception ex)
{
throw ex;
}
}
Thanks,

Hi Dinko and Team,
As I mentioned in the previous forum, We need fix for Raddropdownlist.SelectedIndex.
When we set SelectedIndex=5 or some value in selectedIndexchangedEvent then the recursive call is happening for SelectedIndex. So we need to restrict the recursive call for both Raddropdownlist.DataSource as well as Raddropdownlist.SelectedIdex.
private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
fillIndustryProcess1(); // radDropDownList1.DataSource = dt; when we set Datasource the recursive call is occurring
radDropDownList1.SelectedIdex = 5; // radDropDownList1.SelectedIdex = 5; when we set Datasource the recursive call is occurring
}
public void fillIndustryProcess1(){
try
{
System.Data.DataTable dt = new System.Data.DataTable();
if (dt.Columns.Count > 0)
{
dt.Columns.Add("Industry", typeof(string));
dt.Columns.Add("ID", typeof(int));
dt.Rows.Add("BGL-0", 0);
dt.Rows.Add("BGL-1", 1);
dt.Rows.Add("BGL-2", 2);
dt.Rows.Add("BGL-3", 3);
dt.Rows.Add("BGL-4", 4);
radDropDownList1.DisplayMember = "Industry";
radDropDownList1.ValueMember = "ID";
}
radDropDownList1.DataSource = dt;// Recursive call occurs
radDropDownList1.SelectedIndex = 0;/ Recursive call occurs
}
catch (System.ComponentModel.Win32Exception ex)
{
throw ex;
}
}
Old Forums in which , Telerik team fixed the RadDropDownList .SelectedValue.
Previous forums in which , Telerik team yet to fix for RadDropDownList.Datasource.

Hi Dinko and team ,
Tried to migrate from Visual studio 2010 project along with Telerik.WinControls.UI.dll - Version - 2013.3.1.1127 to Visual studio 2022 with Telerik.WinControls.UI.dll - Version 2023.1.314.
There are random stackoverflow exceptions throughout project. In older version Telerik 2013.3.1.1127 is working with no issues only in Visual studio 2022 Telerick 2023.1.314 creating issue.
Found the RadDropDownList is the root cause So
As Dinko | Tech Support Engineer Telerik suggested in forum tried the below code
cmbValveSize_SelectedIndexChanged -= cmbValveSize_SelectedIndexChanged;
cmbValveSize.SelectedValue = 3;
cmbValveSize.SelectedIndexChanged += cmbValveSize_SelectedIndexChanged;
The stackoverflow is got resolved at this point so we applied the same code wherever SelectedValue getting assigned throughout project but when we call recursive functions the SelectedValue is getting assigned as null since the assigned value is based on value member signature and datasource datatable also having value.
private void setComboBoxIndexChanged(RadDropDownList combobox, object selectedValue, Telerik.WinControls.UI.Data.PositionChangedEventHandler eventHandler)
{
if (eventHandler != null) { combobox.SelectedIndexChanged -= eventHandler; }
if (int.TryParse(Convert.ToString(selectedValue), out int result))
{
combobox.SelectedValue = result; //result having the value but assiging as null
if (combobox.SelectedValue == null && combobox.Name == "cmbValveSize")
{
DataTable dtValues = (DataTable)cmbValveSize.DataSource;
if(dtValues.Rows.Count > 0)
{
}
else
{
}
}
if (eventHandler != null) { combobox.SelectedIndexChanged += eventHandler; }
}
So what is causing in version 2023.1.314 RadDropDownList? why we need to do subscribe and unsubscribe for Telerik 2023.1.314 but not for Telerik 2013.3.1.1127 . What is the change between2013.3.1.1127 and 2023.1.314.
When is the change and Which version will overcome the stackoverflow issue in Visual studio 2022 after 2013.3.1.1127.? - Since we need the latest Telerik version for VS 2022 application.
Unsubscribe and subscribe is not a solution it is affecting the other functionalities of project.
Please suggest what we can do apart from Unsubscribe and subscribe.
Thanks,
Maheswari

We are currently working with Telerik Winforms 2021.1.223.40
and We'd like to seek advice on.
In our Winforms application, we call the Click event of RadRepeatButton.
When occurs the click event of this button, we show Telerik messagebox after certain data checks.
When showing Telerik messagebox, we make layout of RadMessageBox through a method named "SetDesing()".
To this end we call a method name ""RadMessageBox.Show".
The problem occurs after calling "RadMessageBox.Show()". Even though we wrote the code that return after this call, the return does not occur. Instead, It repeatedly triggers the Click event of the RadRepeatButton. (It almost like a recursive function.)
Below are the detailed codes and the call stacks.

Hi,
I have a control that is opened as a floating HostWindow. This control is composed of a RadPageView and a RadPanel and all these elements have the margins and paddings set to 0. Also, BorderStyle properties are set to None but I still see the borders there (see image attached).
There is any way to remove these borders?
