display field of DataGridViewRow

  • 772

I have a DataGridViewRow in my form that has a Notes field but these notes are sometimes written by users very long so the field extends a lot example

enter image description here

How can I make a box where all this text fits or the column expands depending on the text or shows me a dialog box

The modification remained like this but it looks somewhat ugly. There is no way that when you pass the mouse over the notes field, a pop-up window or a bubble appears with the text, if there is one, can you help me?

enter image description here

  1. You must set DefaultCellStyle.WrapModethe column property to DataGridViewTriState.True. After this, the text in the cells will be displayed correctly.

    Example ( DataGridViewwith one column):

    dataGridView1.Columns[0].DefaultCellStyle.WrapMode = DataGridViewTriState.True;
dataGridView1.Rows.Add("Probando" + Environment.NewLine + "Multilinea");

    ( Environment.NewLine= \r\non Windows)

    He DataGridViewhas properties like being:

    DataGridView.AutoSizeColumnsMode Property

    which you must change in order to control the width of columns.

    Could you define the

    DataGridViewCellStyle.WrapMode Property

    so that the content goes to the next line if it exceeds the width set in the column

    To show less information, if you notice that the string is very long, you could truncate it and assign the property

    DataGridViewCell.ToolTipText Property

    of the cell, so when you pass the mouse over it you will see in a ``tooltip` the complete info.

    To truncate you just put a fixed amount of text using

    string contenido = cadena.Substring(0, length);

    In lengthyou define the numerical value of the length that you consider appropriate
