Jagged text in sfDataGrid

[Ahmad]

The text in the sfDataGrid cells and headers appears jagged. I have a native .net dataGridView in the same project set with the same font family, color and size as the sfDataGrid and its text looks smoother. It looks like there's no anti-aliasing applied to the sfDataGrid text. Check the attached images for better understanding.

How can I make the sfDataGrid text smoother?

Hi, here are the answers to your questions:

1.       which device you are using and configuration details?  --> I'm using WinForms on a Desktop

2.       Syncfusion updated version  --> latest version (18.3460.0.35)

3.       Issue reproducing steps or video (if possible) --> See below

4.       Visual studio and .net framework versions  --> VS 2019, .net framework 4.7.2

5.       Share your sample (if possible)  --> Shared. 

The provided VS 2019 project contains two forms: 

Dashboard

Add Delete Departments (this is where the sfDataGrid is located).

Once the application starts, the Dashboard will be loaded first, and then it will automatically load the "Add Delete Departments Form". 

Below are the steps to reproduce the problem:

1- Start the provided solution

2- Minimize the Dashboard form titled "One SpYder", and notice the other form titled "Add Delete Departments".

3- Notice how the font in sfDataGrid is jagged and that the sorting icons are not correct.

4- Stop the application

To fix the problem:

5- Open Dashboard.Designer.cs file

6- Comment out line 811:

this.Controls.Add(this.panel9);  // comment out this line and the problem disappears

Repeat steps 1-3, the text of the datagrid and the sorting icon should now look normal.

Another way to fix the problem:

7- Stop the application

8- Open Dashboard.Designer.cs file

9- Uncomment line 811 if it was commented

10- Comment both lines 322 and 326:

this.panel9.Dock = System.Windows.Forms.DockStyle.Fill; // comment out this line

this.panel9.Size = new System.Drawing.Size(1362, 639); // comment out this line

Repeat steps 1-3, the text of the datagrid and the sorting icon should now look normal.

Hi Dhanasekar,

Actually, the video that you recorded did replicate the problem, but you need to look carefully at the text. Please retry the steps, in the "Add Delete Departments" form, look carefully at the text in the sfDataGrid, and see how the "A" in the last row "Add new department" looks jagged. To help you see the difference, I took a screen shot from your video, and put it side by side with another screen shot that I took it after applying the workaround (commenting out line 811). Notice how the text in your video is jagged while the other one is smooth.

I've also recorded a full video from my computer to show both scenarios: the jagged text and the smooth one.

Dear support, 

I have the same problem - was this problem ever resolved? I believe it must have something to do with High DPI setting or something similar.

Tengo el mismo problema

[Vijayarasan Sivanandham]

Hi Leonardo Buasso,

We have prepared the simple sample in MS and checked the reported problem. The reported problem occurs also while using the Graphics.DrawString method with System.Windows.Forms.DataVisualization.Charting.Chart. So, we have asked query in Microsoft developer community forum. Please find the below link,

MSDN link: https://developercommunity.visualstudio.com/t/text-drawn-using-graphicsdrawstring-method-is-not/1225695

However, as per the answer provided for the query raised in the developer’s community, the reported issue is a GDI+ caching related issue when launching the second form in the Load event of the main form. It occurs only when launching the form in the load event and the workaround suggested to resolve this is not to launch the form in the load event. Kindly change the place of launching the form as suggested in the developer’s community solution.

Please let us know if you have any concerns about this.

Vijayarasan S
