Implementing a Red Cross -Check Box in the Selection Column of the ASPxGridView or general GridView
I am currently using DevExpress ASPxGridView and want the selection check box to show a redcross image on selection or empty when unselected. Is there any javascript library to do such a thing. If so can you provide me an example.
Pelase make sure that your solution would not hinder me to开发者_如何学JAVA perform Callbacks on SelectionChanged Event.
Note: You may give me solutions for general GridView or ASPxGridView.
Ok Guys, I think this is the best possible way to do it.
You can toggele the image of the Select command Button.
<dx:ASPxGridView ID="ChildGridView" runat="server" KeyFieldName="Log_ID" OnCommandButtonInitialize="ChildGrid_CommandButtonInitialize" OnCustomCallback="ChildGridView_CustomCallback" Width="100%" OnHtmlRowPrepared="ChildGridView_HtmlRowPrepared">
<Settings showcolumnheaders="false" gridlines="None" ShowStatusBar="Hidden" ShowPreview="true" ShowTitlePanel="false" />
<SettingsPager ShowEmptyDataRows="false" Visible="false"></SettingsPager>
<Paddings Padding="0px" />
<Border BorderWidth="0px" BorderColor="#cccccc" BorderStyle="None" />
<settingsbehavior />
<clientsideevents selectionchanged="function(s,e){
s.PerformCallback(e.visibleIndex);
}" />
<Columns>
<dx:GridViewCommandColumn ButtonType="Image" ShowSelectCheckbox="false" Name="IsChecked">
<SelectButton Visible="true" >
</SelectButton>
</dx:GridViewCommandColumn>
<dx:GridViewDataTextColumn FieldName="Log_ID" Caption="Log_ID" Visible="false" />
<dx:GridViewDataTextColumn FieldName="Message" Caption="Messages" />
<dx:GridViewDataTextColumn FieldName="IsRuleBad" Caption="IsRuleBad" Visible="false" />
<dx:GridViewDataTextColumn FieldName="Pending_MainTrade_ID" Caption="MainTradeId" Visible="false" />
</Columns>
</dx:ASPxGridView>
Code Behind:
protected void ChildGrid_CommandButtonInitialize(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewCommandButtonEventArgs e)
{
string appPath = HttpContext.Current.Request.ApplicationPath;
ASPxGridView childGrid = sender as ASPxGridView;
if (e.ButtonType != DevExpress.Web.ASPxGridView.ColumnCommandButtonType.Select) return;
bool isRowSelected = childGrid.Selection.IsRowSelected(e.VisibleIndex);
if (isRowSelected)
{
e.Image.Url = appPath + "/images/votedown.png";
}
else
{
e.Image.Url = appPath + "/images/voteup.png";
}
}
