I would like to add a CheckboxColum to a Gridview, I am completely stuck. I does not work in WPf
var gridView = new GridView();
GridViewColumn col = new GridViewColumn();
col.Header = "Colum ";
col.Width = 100;
col.CellTemplate = (DataTemplate) ......
col.DisplayMemberBinding = new Binding("BooleanData");
gridView.Columns.Add(col);
I'm stuck here
col.CellTemplate = (DataTemplate) CheckBox ....
You just need to change this line ...
GridViewColumn col = new GridViewColumn();
to this (WinForms)
CheckBoxColumn checkCol = new CheckBoxColumn();
or this (WPF)
CheckBoxColumn checkCol = new DataGridCheckBoxColumn();
Here is a list of all column types http://msdn.microsoft.com/en-us/library/bxt3k60s.aspx
Create a class with the below given code:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;

using System.Web.UI.HtmlControls;
using System.ComponentModel;
using System.Collections;

}
}
}
}
private String GetType(String ColumnName, GridViewRow row)
{

clsSearch obj = new clsSearch();
// i have set up the table name static as now we require to make search working for macintosh project only.
// as per rakesh sir directed.

switch (Type)

case 1:

}
private Control CloneControl(System.Web.UI.Control src_ctl)
{
Type t = src_ctl.GetType();
Object obj = Activator.CreateInstance(t);
Control dst_ctl = (Control)obj;
PropertyDescriptorCollection src_pdc = TypeDescriptor.GetProperties(src_ctl);
PropertyDescriptorCollection dst_pdc = TypeDescriptor.GetProperties(dst_ctl);
for (int i = 0; i < src_pdc.Count; i++)
{
if (src_pdc[i].Attributes.Contains(DesignerSerializationVisibilityAttribute.Content))
{
object collection_val = src_pdc[i].GetValue(src_ctl);
if ((collection_val is IList) == true)
{
foreach (object child in (IList)collection_val)
{

}
else
{
dst_pdc[src_pdc[i].Name].SetValue(dst_ctl, src_pdc[i].GetValue(src_ctl));
}
}
return dst_ctl;
}
}
and use it like the below:
TemplateField t = new TemplateField();
DynamicTemplate mt = new DynamicTemplate(ListItemType.Item);
mt.TableName = TableName;
if (IsEditButtonVisible == 1)
{
Image ibtnEdit = new Image();
ibtnEdit.ID = "btnEdit";
ibtnEdit.CssClass = "EditButton";
ibtnEdit.ImageUrl = EditButtonImageSrc;
ibtnEdit.Style.Add("cursor", "pointer");
ibtnEdit.ToolTip = "View Details";
mt.AddControl(ibtnEdit, "AlternateText", "Id");
}
if (IsDeleteButtonVisible == 1)
{
Image ibtnDelete = new Image();
ibtnDelete.ID = "ibtnDelete";
ibtnDelete.CssClass = "DeleteButton";
ibtnDelete.ImageUrl = DeleteButtonImageSrc;
mt.AddControl(ibtnDelete, "AlternateText", "Id");
}
t.ItemTemplate = mt;
t.HeaderText = "Activity";
t.HeaderStyle.HorizontalAlign = HorizontalAlign.Left;
GridView1.Columns.Add(t);
}
GridView1.DataSource = dtOutPutResult;
GridView1.DataBind();
I am adding buttons in the same you can do it for checkbox
