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 want to build a DataGridView, which if I choose one of the item of a DataGridViewComboBoxCell, then the other cells in the same row which should be TextBoxes in other rows will turn into ComboBoxes,does anyone knows how to do that?
It is like:
TextBox1|TextBox2|ComboBox1.Item1|TextBox3 |TextBox4 |TextBox5 |TextBox6
TextBox1|TextBox2|ComboBox1.Item3|TextBox3 |TextBox4 |TextBox5 |TextBox6
TextBox1|TextBox2|ComboBox1.Item2|ComboBox3|ComboBox4|ComboBox5|ComboBox6
If you want to do something when the Value in a DataGridViewCell changes then you should handle the CellValueChanged event of the grid.
If you want to place a cell of a specific type in a specific location in a DataGridView then you can do so using the grid's indexer, e.g.
myDataGridView[columnIndex, rowIndex] = new DataGridViewComboBoxCell();
In summary, handle the CellValueChanged event, use an if statement to test whether the Value is one that corresponds to a text box or combo box and, if the types of the other cells are not what they should be, replace them.
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 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.
i am using a web application gridview on my page...
I want to get the selected(mouse clicked) cell text value & also which event i want to use?..!
use SelectedIndexChanged event.
I am not sure about cell, but you can definitely get the selected row. First of all, set the allow selection property to true. Second, go in events and there should be an event called SelectedIndexChangedThis would allow you to do something when the selected index is changed. Then, using
gridvidew1.Rows[gridView1.selectedindex]
you will be able to get the selected row. User can select the row by using the select link placed automatically against each row.
Hope this helps,
New to .NET/C# stuff so please forgive me if it's something obvious ;-) I'm trying to get cell editing going on a DataGridView control (WinForms). I've set all "ReadOnly"-type options to false, I've set EditMode to "EditOnEnter", I've added a row and selected a current cell programmatically, I've tried calling BeginEdit() but all to no avail - I can't edit the cell's contents.
The only thing that I can think of is that the control isn't bound to a data source - I'd like to be able to use it in a spreadsheet manner, so as the contents are typed in, I can then add new rows etc, and on a button click, the data can be retrieved programmatically for later use.
Is this possible?
Thanks,
Rich
I do that all the time (i.e. allowing users to edit a column without the DataGridView being bound).
Try this:
Set EditMode to EditOnKeystrokeOrF2
Ensure ReadOnly on the DataGridView is set to false
Ensure that ReadOnly on the column you want to edit is set to false
That should work.
