HI Following is my Aspx file for Select all checkbox :-

<dxwgv:ASPxGridView ID="gvIndexSecurity" runat="server" AutoGenerateColumns="False"

                                                   DataSourceID="sdsUnassignedAnalyst"

                                                   KeyFieldName="PKAnalystIndustryID" OnDataBound="gvIndexSecurity_DataBound">
                                                    <SettingsPager PageSize="15" Position="TopAndBottom">
                                                   </SettingsPager>
                                                  <Columns>
                                                       <dxwgv:GridViewCommandColumn Caption="Select" ShowSelectCheckbox="true"  VisibleIndex="0">
                                                         <ClearFilterButton Visible="true">
                                                           </ClearFilterButton>
                                                           <HeaderTemplate>
                           <asp:CheckBox ID="chkboxSelectAll" runat="server" AutoPostBack="true" OnCheckedChanged="chkAll_CheckedChanged" />
                       </HeaderTemplate>
                                                       </dxwgv:GridViewCommandColumn>

Aspx.CS代码

Aspx.CS code

protected void chkAll_CheckedChanged(object sender, EventArgs e)
   {
       //CheckBox chkAll = (CheckBox)gvIndexSecurity.FindHeaderTemplateControl(gvIndexSecurity.Columns[1], "chkAll");
       CheckBox chkAll = (CheckBox)gvIndexSecurity.FindHeaderTemplateControl(gvIndexSecurity.Columns[0],"chkboxSelectAll");
       if (chkAll.Checked)
       {
           gvIndexSecurity.Selection.SelectAll();
       }
       else
       {
           uncheckAll();
       }
   }

private void uncheckAll()
   {
       gvIndexSecurity.Selection.UnselectAll();
       //chkAll.Checked = false;
   }

选择全部不适合我。请帮忙。
