I use GridView in my C# application, and the cell seems too small.
I find the prop of GridView, but I find nothing about it. How can I display all text in Cell?
Under Columns Collection property there is AutoSizeMode under Layout. And use for example DisplayedCells and see for yourself.
For Word Wrap you could set it programmatically like:
// Columns[1] for 2nd column based on your example.
dataGridView.Columns[1].DefaultCellStyle.WrapMode = DataGridViewTriState.true;
But don't set the AutoSizeMode as above or else the columns will still expand.
You could set it also manually under Columns Collection property and under Appearance select Default Cell Style and then set WrapMode to true.

This Grid column property i can set from the designer, but not from the C # code !!! Why? Header.BackColor is working fine. I can also set any other color for the GridView elements except this.
If you are doing this at runtime you need to set the GridColumn.AppearanceHeader.Options.UserForeColor property to true as well as set the actual color. When you do this via the designer, the property is automatically set to true.
gridView1.Columns["FieldName"].AppearanceHeader.ForeColor = Color.Red;
gridView1.Columns["FieldName"].AppearanceHeader.Options.UseForeColor = true;
Ref: How do I set the color of a grid column header panel?
The header's BackColor property is ignored in the Skin paint style.
Add the following line to your code to address this issue:
gridControl1.LookAndFeel.Style = DevExpress.LookAndFeel.LookAndFeelStyle.Flat;
gridControl1.LookAndFeel.UseDefaultLookAndFeel = false; // <<<<<<<<
gridView1.Appearance.HeaderPanel.Options.UseForeColor = true;
gridView1.Appearance.HeaderPanel.ForeColor = System.Drawing.Color.Red;

Why Appearance settings of DevExpress controls are not taken into account?
Devexpress column header color (each column different color), winform c#
The DevExpress skinning mechanism overrides the Appearance object settings. You have a couple options if you need a different background color for the column header:
Disable skinning on the GridControl by setting the GridControl.LookAndFeel.UseDefaultLookAndFeel property to False and the GridControl.LookAndFeel.Style property to "Flat".
Handle the GridView's CustomDrawColumnHeader and fill the column header with a different color.
How to make a Row select highlight specific Cells and not all the Row in a Grid View. I have explored all the questions on SOF, but there is nothing is available.
Set the SelectionMode property of the Grid to CellSelect
You need the set the selection mode on the Grid to cell selection.
If you want it to act like a row select but keep a few cells un-highlighted you should use CellSelect as the selection mode. Then register on row selection changed and set the cell.Selected = true; for the ones you want selected, and false for the rest.
I found the solution !! If you want to control the highlight of a row to a certain range of cells, then you need to control the behavior of the cells in question and make them behave differently when the a row is selected.
YourGridviewInstance.GetCellRange(int topRow,int leftColumn,int buttomRow,inr RightColumn)
in other words
YourGridviewInstance.GetCellRange(YourCurrentRow, The column you want to affect,YourCurrentRow, The Same Column you want to affect)
I want to hide specific cells in gridview. I have a view that is generated that has a delete column. I want the delete column there so I cant hide the entire thing using:
Gridview.Columns[3].Visible = false;
But if the row was generated before a certain date I don't want the delete cell to show up in that row. I already have the logic to check this but how do I hide the actual specific cell?
Assign empty string to cell, you can not hide single cell with server code.
Gridview.Rows[3].Cell[index].Text = "";
OR, clear all controls in the cell.
Gridview.Rows[3].Cell[index].Controls.Clear();
Add some logic into the GridView's RowDataBound event handler to make the cell's content visible or not.
A Good example on MSDN Link
You don't need to hide the cell. Just make the content invisible.
So, you could set the content to an empty string, or you could set the IsVisible (or similar) property on whatever control you may have in the cell.
I have a datagridview bound to a datasource, and in each row in the grid there is a category, product, and quantity. I want to filter the products in each row according to the selected category.
I'm using C# and DevExpress. How can I do this?
Please refer to the How to filter a second LookUp column based on a first LookUp column's value article which explains how to implement this feature.
Depending on how You want to filter you can set
gridView1.OptionsCustomization.AllowFilter = true;
This will display an additional filter row in your grid that will allow you to filter all columns by any text you want;
Or you can make sure that gridView1.OptionsCustomization.AllowFilter is set to true. Then there should be little icon on your column header (visible in right top corner when you move cursor over the column header) that will display filter after you click it.
I am using DataGridView component in Windows Forms .Net. How to break line into column? "\n\r" doesn'work.
Edit the column, edit the DefaultCellStyle property and set the WrapMode property to True. And change the DGV's AutoSizeRowMode to, say, AllCells so that a row automatically grows in height to fit the text. The text in the column header and the cells will now automatically word-wrap. You can use "\n" to force an early wrap.
