Fix row height of every row in TableLayoutPanel

c#, row-height, tablelayoutpanel, winforms

Solution

I'm still new to tableLayoutPanels myself, but I noticed that at the bottom of your code, you're Clearing all the rowstyles from the collection, then you're trying to iterate through them in your foreach loop.

You did this:

tableLayout.RowStyles.Clear();   //now you have zero rowstyles

foreach (RowStyle rs in tableLayout.RowStyles)   //this will never execute
    tableLayout.RowStyles.Add(new RowStyle(SizeType.AutoSize));

Try this instead.

TableLayoutRowStyleCollection styles =
    tableLayout.RowStyles;
foreach (RowStyle style in styles){
    // Set the row height to 20 pixels.
    style.SizeType = SizeType.Absolute;
    style.Height = 20;
}

Edit: I just realized that adding N rows doesn't add N rowstyles that you can iterate through. I think what's happening is that you're adding N rows, but none of them have a rowstyles.

I suppose you can Clear() the rowstyles, then just add N rowstyles similar to how you're already doing.

Problem

I'm working on Windows c#. Firstly, the things those can not be change as my need are following: - The Size of `TableLayoutPanel` is fixed. - The Total # of columns are fixed. Now, I want to set a fix height for all rows but as increasing the rows, if I set the `RowStyle` property to `Percent` with `100.0F` then it works fine for 3 to 4 items, but after 4-5 items, the control on one row overwrites controls on another row. I have searched for this so more but i'm not able to get the proper answer. I have also tried the `AutoSize`, `Percent`, `Absolute` properties of `RowStyle`, even though it is not working. So what to do and how? How can I achieve this? Ultimately, I want to do same like as `DataGridView` of Windows C#. Thanks in advance.... I'm working on WinForms...the sample code is here.. ``` int cnt = tableLayout.RowCount = myDataTable.Rows.Count; tableLayout.Size = new System.Drawing.Size(555, 200); for (int i = 1; i <= cnt; i++) { Label lblSrNo = new Label(); lblSrNo.Text = i.ToString(); TextBox txt = new TextBox(); txt.Text = ""; txt.Size = new System.Drawing.Size(69, 20); tableLayout.Controls.Add(lblSrNo, 0, i - 1); tableLayout.Controls.Add(txt, 1, i - 1); } tableLayout.RowStyles.Clear(); foreach (RowStyle rs in tableLayout.RowStyles) tableLayout.RowStyles.Add(new RowStyle(SizeType.AutoSize)); ``` The label and textboxes are working fine for 4-5 #of rows but whenever the #of row(in this case, variable cnt in for loop) increases, the rows are overwriting each other that is one control overwrite to another...I had drag-drop the TableLayoutPanel control and created just one row and 2 columns manually. So please tell me how to do it.
