columns appearing multiple times in datagridview

Question

columns appearing multiple times in datagridview

rahul kumar 605

I have created a CustomDatagridview by the following

   public partial class Paymentdatagridview : DataGridView
        {
            cusList = new Dictionary<string, string>();
            cusList.Add("deepak(market)", "21.00");
            cusList.Add("xxx(market)", "10.00");
            // i have set enableheadervisualstyles to false 
            // make bold the headers
            // Add the columns to your custom DataGridView
            DataGridViewColumn column1 = new DataGridViewTextBoxColumn();
            column1.Name = "Column1";
            column1.HeaderText = "Particulars";
            column1.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
            column1.SortMode = DataGridViewColumnSortMode.Automatic;
            this.Columns.Add(column1);

            DataGridViewColumn column2 = new DataGridViewTextBoxColumn();
            column2.Name = "Column2";
            column2.HeaderText = "Amount";
            column2.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
            column2.SortMode = DataGridViewColumnSortMode.Programmatic;
            this.Columns.Add(column2);

            this.RowHeadersVisible = false;
            this.ColumnHeadersDefaultCellStyle.Font = new Font("Tahoma", 9.75F, FontStyle.Bold);
            this.CellBorderStyle = DataGridViewCellBorderStyle.None;
            this.AllowUserToAddRows = false;
            InitializeComponent();
        }

and used it in my form named by drag and drop ( after clean solution and Rebuilt solution , then after closing the file and opening again ) but i found out that the column names are appearing twice . I tried draging the control again from the toolbox but the same problem happens to the other customdatagridview as well . below is the codebehind and designer file

Hi @Rahul Kumar , Welcome to Microsoft Q&A.

Use Ctrl+F to quickly query the paymentdatagridview in your code.

You added a Paymentdatagridview repeatedly, is this necessary?

this.Controls.Add(this.paymentdatagridview2); this.Controls.Add(this.paymentdatagridview1);

Removing one of them should fix your problem.

If it doesn't work, I suggest you give the complete code, your code seems to be missing.

@Anonymous yes it is required in the case if I want two paymentdatagridview on my form. Removing one of them will remove one paymentdatagridview from my form instead of columns appearing twice

Hi @Rahul Kumar , Welcome to Microsoft Q&A.

After careful testing, Designer will add column again when dragging into datagridview custom control.

The current emergency solution is: manually delete this.paymentdatagridview.Columns.AddRange in the designer code add page.

In testing, this problem occurs with both .Net and Framework.

I'll keep researching to see if it's a bug.

Hi @Rahul Kumar , Did this solution solve your problem?

@Anonymous , it did solve my problem but I found out that as soon as i make some changes in the datagridview size , it again automatically uncomment(i didn't delete , i comment out the lines) the this.paymentdatagridview.Columns.AddRange Line in the designer code(which you suggested) and add the columns again and again and again . Have you find out the solution ? Is it a bug ? Should I mark your answer as accepted . By accepting will you get back to me if you found the solution for this or if you find it as a bug ?

Hi @Rahul Kumar , This issue is discussed as a bug. It is recommended that you could report the problem in the Developer Community. I will also make corresponding records.

There is another way that you don't add it through custom datagridview, add it separately in the project. Currently you may need to comment out the corresponding added code after the last modification. If you go to DC and ask a question, please paste the link here and I will make a note of it.
