如何在DevExpress中使用回调 [英] How to use callback in DevExpress

问题描述

我是使用DevExpress的新手，首先感谢您查看我的问题。



这是我的问题：





我创建了一个ASPxButton来隐藏/显示一个panelgraph，这里是我写的代码：

Hi, I''m new in using DevExpress, thank you first of all for checking my question.

Here is my problem:


I created a ASPxButton​ to hide/show a panelgraph, here are codes that I wrote:

<dx:ASPxButton ID="btHideShowChart"  runat="server" Text="Hide the chart" 
                                                                             önclick="btHideShowChart_Click" >
                                                                           <ClientSideEvents Click="function(s, e) {
                                                                                if(s.GetText().toString()== ''Hide the chart''){
	                                                                            callbackPanelGraph.SetVisible(false);
	                                                                            }
	                                                                            else{
	                                                                            callbackPanelGraph.SetVisible(true);
	                                                                            }
                                                                            }" />

同时，我写道：

at the same time, I wrote :

protected void btHideShowChart_Click(object sender, EventArgs e)
        {
            if (btHideShowChart.Text.ToString() == "Hide the chart")
            {
                btHideShowChart.Text = "Show the chart";
                return;
            }
            if (btHideShowChart.Text.ToString() == "Show the chart")
            {
                btHideShowChart.Text = "Hide the chart";
                return;
            }
        }

它运作良好。但现在，我希望一旦图表被隐藏，旁边另一个Panel的宽度可能会比以前更大。 （有两个对齐的面板：我想要显示/隐藏的panelChart和panelDetail，当panelChart被隐藏时，我想让它更大。）



我试过回调..但它不起作用....





谢谢非常有帮助!!

it does work well. But now, I''d like that once the chart is hidden, the width of another Panel beside​ could be bigger than before. ( There are two panels which are aligned: panelChart which I''d like to show/hide and panelDetail which I''d like to make it bigger when the panelChart is hidden. )

I''d tried callback..but it doesn''t work....


thank you so much for helping!!​
