Q: How can I put a checkbox in a column of my DataGrid?(.net winform)You create a custom DataTableStyle that contains column styles for each column you want to display. You add the column styles in the order you want them to appear. Here are the steps to add an string column, an int column and a bool check column to a DataGrid. You can also download a working project.
// code assumes you have a DataSet named myDataSet, a table named "EastCoastSales" and a DataGrid myDataGrid
//STEP 1: Create a DataTable style object and set properties if required.
DataGridTableStyle ts1 = new DataGridTableStyle();
//specify the table from dataset (required step)
ts1.MappingName = "EastCoastSales";
// Set other properties (optional step)
ts1.AlternatingBackColor = Color.LightBlue;
//STEP 2: Create a string column and add it to the tablestyle
DataGridColumnStyle TextCol = new DataGridTextBoxColumn();
// code assumes you have a DataSet named myDataSet, a table named "EastCoastSales" and a DataGrid myDataGrid
//STEP 1: Create a DataTable style object and set properties if required.
DataGridTableStyle ts1 = new DataGridTableStyle();
//specify the table from dataset (required step)
ts1.MappingName = "EastCoastSales";
// Set other properties (optional step)
ts1.AlternatingBackColor = Color.LightBlue;
//STEP 2: Create a string column and add it to the tablestyle
DataGridColumnStyle TextCol = new DataGridTextBoxColumn();
TextCol.MappingName = "custName"; //from dataset table
TextCol.HeaderText = "Customer Name";
TextCol.Width = 250;
ts1.GridColumnStyles.Add(TextCol);
//STEP 3: Create an int column style and add it to the tablestyle
//this requires setting the format for the column through its property descriptor
PropertyDescriptorCollection pdc = this.BindingContext
[myDataSet, "EastCoastSales"].GetItemProperties();
//now created a formated column using the pdc
DataGridDigitsTextBoxColumn csIDInt =
new DataGridDigitsTextBoxColumn(pdc["CustID"], "i", true);
csIDInt.MappingName = "CustID";
csIDInt.HeaderText = "CustID";
csIDInt.Width = 100;
ts1.GridColumnStyles.Add(csIDInt);
//STEP 4: Add the checkbox
DataGridColumnStyle boolCol = new DataGridBoolColumn();
boolCol.MappingName = "Current";
boolCol.HeaderText = "Info Current";
//uncomment this line to get a two-state checkbox
//((DataGridBoolColumn)boolCol).AllowNull = false;
boolCol.Width = 150;
ts1.GridColumnStyles.Add(boolCol);
//STEP 5: Add the tablestyle to your datagrid's tablestlye collection
myDataGrid.TableStyles.Add(ts1);
checkboxCol_Columncheckbox_click(object sender, System.EventArgs e)
{}只要你找到这个checkbox即可,其实它只是嵌套了,还是checkbox,没有太大 的变化的。
还有我发现现在选中一个checkbox要在单元格里点两下才行,第一下选中单元格第二下才选中checkbox,能改成一次就选中checkbox吗?
