Refer to the documentation above to embed chromium browser in WinForm.

Problem statement:

Whenever I embed the CefSharp Web Browser, the formatting changed. 

Observation - With embedded CefSharp Web Browser: 

• Window State set to Maximized but it won't start with Maximized state.
• The formatting of the words seems changed - truncated with '...'

using CefSharp;
using CefSharp.WinForms;
 
private ChromiumWebBrowser browser = new ChromiumWebBrowser();


 private void frmBulletin_Load(object sender, EventArgs e)
        {
            Cef.Initialize(new CefSettings());
            pnlBrowser.Controls.Add(browser);
            browser.Dock = DockStyle.Fill;
        }

Hello.

I am developing a form that has a radgrid with hierarchy and in some instances, the parent row makes changes to the child rows and vice versa.
In my case, I have the functionalities below (Among others):

1. Both the parent and child rows have a "Check" column.
2. The relation between the 2 is done through an "Id" column which in my DataSource, is a Guid (The column in both templates is a textbox).
3. Every time a row is checked (Parent or child), the background changes color.
4. Every time I check a parent row, the corresponding child rows are also checked (Which then change color).
   Same happens if I uncheck the parent row which then unchecks the corresponding child rows and resets the background color.
   This behavior is managed in the CellValueChanged event of the RadGridView.
   Checking and unchecking the child rows according to the parent, is being done directly in the DataSource which in my case is a DataTable. But the same behavior happens if I edit the grid rows directly.
5. In the parent template, the Check column has the property EnableHeaderCheckBox set to true.
6. The color rule is managed by a ExpressionFormattingObject added to the ConditionalFormattingObjectList property of the Check column. I also tried to set up the color rules in the Formating events but the problem I will explain below persists. Still, the color is not the only problem.
   

My problem here is that everything works correctly if I check and uncheck the parent rows individually. Whether they expanded or not. Depending on the check action in the parent row, the child rows update visually both in their "Check" state and in the color rule.



However, if I check/uncheck all the parent columns from the header check box, the child rows do not update visually unless I close the parent row and expand it again or if I click on all rows/scroll down or up to force them to update.
Like in this print for example. The first parent row was expanded when I checked the header check box. It was suppose to check the child rows and update the color. They are checked internally in the datasource.



There are also some issues with the header check in the child rows. In this case, I do not have the EnableHeaderCheckBox = true in the GridViewTemplate but the problem is similar. Checking all the child rows of a certain parent row through the header check, updates the value on the "Chk" column but does not update it visually with the color.

There is also a problem where in some instances if I check all the parent rows through the header check box, their color does not update.
This happens regardless of the parent rows being expanded or not.



I have to click on each one or scroll or expand them to force the visual update.
The problem seems to be related to the actual visual update. I tried multiple things to for the update but none helped. Also tried forcing the rows to expand if they were collapsed not none helped.

This is all I tried.


On all the examples, I checked the data in the datasource and everything is updated correctly. It is just the visuals that are not updating automatically.

To help understand the problem, I attached a little example with a solution similar to what I have, where this issue can be replicated.
I am using Telerik Winforms V2024.4.1113.462.

Thank you in advance for any answer.

Hello,

I have a issue with print datagridview by a larger number of columns.

In first case (WratText = false) I cannot see all text (see image)

In the second case (WrapText = true) is row height too small and again I cannot see whole text.

Both case it has set AutoSizeRows = true;

In both cases I don't see the entire date

 Can you help me?

Thank you

Hello,

I want to choose column by checkboxes, something like that:

I

It is possible?

Thank you for your answer

Simple question: I want to change the color of some tasks, to show when they are on the critical path.

So I simply want to trigger GraphicalViewItemFormatting, which does all the coloring. At the monent, the event fires when i move the mouse over the task ,which proves it all works, but I need to trigger the re-draw from my calculateCritcalPath method. 

I'm using the VisualStudio2022Dark and VisualStudio2022Light themes for my application.

I've used the waitingbar on a couple of longer loading controls (works great BTW).

However the overlay that appears over a control while waiting, always appears to be the light theme color.  On a dark theme, this is can be pretty visually jarring, especially when the associatedControl is a larger screen control.

Is there a way to set this overlay so that it uses a specific theme?  I haven't been able to get it to change at all programmatically.

On the gridview when a user enters a filter value, I would like for the background color of that filter to change to a different color (only for the column or columns where a filter has been entered) so that users can quickly see where they entered a filter value.

Currently, if the grid has many columns the user will enter a value (sometimes forget that they did that) and wonder why they have a filtered grid.  I know that sounds crazy but end users do that!  So, I'd like the Filter Cell Backcolor to be a different color so that it's Obvious that - that particular column has a filter applied to it.

Below, I show the code I'm using in the GridData_ViewCellFormatting event.  But the problem is - is that it changes the color for the entire filtering row (across all columns)... whereas I want the back color of the "Filter Cell" to change only for that particular column or columns where a filter has been applied.

It would be greatly appreciated is someone has the answer to solving this 'problem'.
