datagridviewcomboboxcell

I am using the ( EditingControlShowing ) event to Enable AutoComplete in DataGridViewComboBox Column. private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { if (e.Control is DataGridViewComboBoxEditingControl) { ComboBox combo = (ComboBox)e.Control; ((ComboBox)e.Control).DropDownStyle = ComboBoxStyle.DropDown; ((ComboBox)e.Control).AutoCompleteSource = AutoCompleteSource.ListItems; ((ComboBox)e.Control).AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend; } } But it has a strange behavior, when I type some characters

I'm currently trying to add a ComboBox to a dataGridView. In the DGV, there are 5 columns: checkbox, string, string, combobox, combobox. both combobox-columns are configured as datagridviewcomboboxcolumns (via VisualStudio designer). My problem is to add rows. My current try is: the columns are already defined and I add rows via dataGridView.Rows.Add. For that, I'm using an array of objects. Example: dataGridViewRow row = new dataGridViewRow(); object[] obj = new object[5] {true, "str1", "str2", null, null}; dataGridView1.Rows.Add(obj); This passes without any errors. But logically, the

When you add a ComboBoxColumn in DataGridView , I do not know how to handle the change event of ComboBox . 'Adding To DGV data on form load Dim cmbovoce As New DataGridViewComboBoxColumn() cmbovoce.HeaderText = "Fruit" cmbovoce.Name = "cmbovoce" cmbovoce.MaxDropDownItems = 4 cmbovoce.Width = 100 cmbovoce.Items.Add("apple") cmbovoce.Items.Add("pear") cmbovoce.Items.Add("cherries") cmbovoce.Items.Add("plums") DataGridView1.Columns.Add(cmbovoce) I strongly recommend you to use Cell events, such as CellValidating , CellValueChanged , ... to detect changes. The combobox that you are trying to

My application consist of DataGridviewComboBoxColumn inside DataGridView . The ComboBoxColumn s are getting filled from a database table (key, value pair). I am trying to set the default value for ComboBox column using DefaultValuesNeeded event but it is not working.

For example: DataGridViewComboBoxColumn dgvCbJob = new DataGridViewComboBoxColumn(); { dgvCbJob.HeaderText = "Job"; hadd.Clear(); hadd.Add("@Search",

I want to create a datagridview with comboboxcolumns using c#. The problem is that I dont know how to give different values for combobox in each row. DataTable dt = new DataTable(); dt.Columns.Add("state"); dt.Columns.Add("city"); dt.Rows.Add("a1", "b1"); dt.Rows.Add("a1", "b2"); dt.Rows.Add("a2", "b3"); dt.Rows.Add("a2", "b4"); dt.Rows.Add("a3", "b5"); DataGridViewComboBoxColumn comboStates = new DataGridViewComboBoxColumn(); comboStates.HeaderText = "HeaderText_1"; this.dataGridView1.Columns.Insert(0, comboStates); DataGridViewComboBoxColumn comboCities = new DataGridViewComboBoxColumn();

After I set "EditOnEnter" to be true, the DataGridViewComboBoxCell still takes two clicks to open if I don't click on the down arrow part of the combo box. Anyone have any clue how to fix this? I've got my own DataGridView class that I use, so I can easily fix this issue system-wide with a few smart event handlers I hope. Thanks. Since you already have the DataGridView 's EditMode property set to "EditOnEnter", you can just override its OnEditingControlShowing method to make sure the drop-down list is shown as soon as a combo box receives focus: public class myDataGridView : DataGridView {
