[英]ASPxGridView error with checkbox
I have one grid with checkbox. 我有一个带有复选框的网格。 Sometimes, when select row and click ADD button it's not work and debugger show me that haven't selected row. 有时,当选择行并单击“添加”按钮时,它不起作用,调试器会向我显示尚未选择的行。 This is a code: 这是一个代码:
protected void GridView_CustomCallback(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewCustomCallbackEventArgs e)
{
ASPxGridView grid = sender as ASPxGridView;
List<object> ids = grid.GetSelectedFieldValues("ID");
if (ids.Count > 0)
{ ......... }
}
SelectAllCheckbox _SelectAll;
if (!(MyGV.Columns[0] is GridViewCommandColumn))
{
_SelectAll = new SelectAllCheckbox() { GridClientInstanceName = MyGV.ClientInstanceName };
Common.AddCommandColumn(MyGV, 0, _SelectAll);
}
Hope this helps. 希望这可以帮助。 Here the event RowDataBound is used. 这里使用事件RowDataBound。
private string chkGridColHeaderId = string.Empty;
protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
CheckBox chkAll = (CheckBox)e.Row.FindControl("chkSelectAll");
chkAll.Attributes.Add("onclick", "SelectAll(this.checked)");
chkGridColHeaderId = chkAll.ClientID;
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox chkSelect = (CheckBox)e.Row.FindControl("chkSelect");
chkSelect.Attributes.Add("onclick", "if(!this.checked)document.getElementById('" + chkGridColHeaderId + "').checked = false;");
}
}
