[2005] Make A DataGridView's Column A Combo ONLY In The "new Row" And A Read Only Textbox In All Other Rows?
Jan 21, 2009
Is there a way to make a DataGridView's column a combo ONLY in the "new row", and a read only textbox in all other rows? I want the user to be able to make a selection from the combo box, and when the row is finished and the "new row" moves down one, I want the column to become a textbox containing the what the user selected. My grid will be bound to a table witch contains a "category" column, that is drawn from a seccond table that i want the combo box bound to.
In my window application i have taken one combobox field with its collection as "amc", "war" etc. Now in my datagridview this combobox column is display as Textbox column, i want to change it to combobox with the above collection "amc","war". I have retreiving the result in datagrid through sql query, hence in datagrid edit column section we doesnot have that part to change to Combobox column.

i have a datagridview with three columns. i set the first column to visible=false, so the user can only see two columns.when the user presses the tab key in the first visible column -- column(1), i want to ignore column(2) so that the user only tabs through the rows in column(1)i can't get it to work. it will always tabs through the rows in column(2) even if i use the column name.
I have a standard DataGridView. One of the columns is aDataGridViewComboBoxColumn. When I select one of the ComboBox items, I wantto trap the change and add text in other column based on the data selected
I want to add a combo box to a column in a datagridview.It is displaying OK and the dropdowns are OK, but how do I get it to display the actual value in the box/cell?
With cmbLdecs .HeaderText = "L Decs" .Width = 60 .Items.Add("No")
But this code will add columns to every rows in the gridview. How can I change the code so that it only add the column to row one instead of every row?

I have a Data Table Column with multiple Rows of data. I need to search all lines of TextBox1.Text for any data that is identical to any row in the specified data column ("MCaddRG"). Also any identical findings need to be made into a new text file or a new form with a text box.[code]...

I'm trying to populate a datagridview with rows in the sqlserver 2005.how to use DataAdapters too well so I go back and forth between hard code and controls.I used the Datagridview control and added columns to it this way. 2 combo boxes, a check box, and 2 text boxes.The 2 combo boxes are populated with values that are already in sql Server for users to pick from. The task is displaying the description while the value is the task_ID. Here is my form on load:
Private Sub frmTimeSheet_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load currentDate = Date.Now.ToShortDateString lblDate.Text = currentDate
I see the DataGridView control has a property "AllowUserToAddRows" that I can turn on or off but what if I want the ability to be context dependent. i.e. I want an event that will fire when the user attempts to add a row in which I can cancel if certain conditions aren't met but I can't find an appropriate event.
i want to save into my sql server 2000 database multiples rows of a datagridview. i tryed something that first was working good, but i did a code change removing a column so now i'm trying to save again but i can't do it.

I rewrite the code, delete and add a new table and my code has the same values in the insert than my values clause. I don't know what else i have to do.
Here is my code
Private Sub cmdAceptar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAceptar.Click Try

Or is there an easier way to save and restore the rows?
VB6 had a feature for it's datagrid where the user could use the mouse to drag the row divider in a datagrid and when the user released the mouse button, all the rows in the datagrid would resize to match the one the user resized (Excel does the same thing if you have all rows highlighted).
