如何使用button to serverclick从gridview中的行获取值？

这是我的代码：

<dx:ASPxGridView ID="gvwListApprover" runat="server" Width="460px">
                <Columns>
                    <dx:GridViewDataTextColumn Caption="No" FieldName="Sequential" Width="20px"></dx:GridViewDataTextColumn>
                    <dx:GridViewDataTextColumn Caption="KodePosition" FieldName="KodePosition" Width="175px"></dx:GridViewDataTextColumn>
                    <dx:GridViewDataTextColumn Caption="Jabatan" FieldName="NamaPosition" Width="175px"></dx:GridViewDataTextColumn>
                    <dx:GridViewDataTextColumn Caption="Nama" FieldName="UserLogin" Width="265px"></dx:GridViewDataTextColumn>
                    <dx:GridViewDataTextColumn ReadOnly="True" Caption="Action">
                        <DataItemTemplate>
                           <input type="button" id="btnDelApp" onserverclick="btnDelApp_ServerClick('<%#Eval("KodePosition")%>');" value="Delete" runat="server" class="lookupstyle" />
                        </DataItemTemplate>
                    </dx:GridViewDataTextColumn>
                </Columns>
            </dx:ASPxGridView>

来自onserverclick，我希望得到代码隐藏的价值。

protected void btnDelApp_ServerClick(object sender, EventArgs e)
{
    //how to get value from row in gridview event button on serverclick ?              
}

请纠正并给我解决方案。感谢

U可以使用点击的RowDataBoundEvent。不要为控件添加任何explict事件。 GridView自动检测在其中单击的控件的事件。

protected void grdClickDoubleClick_RowDataBound(object sender, GridViewRowEventArgs e) //formatted the c# code

{ 

     GridViewRow row = e.Row;

     if (row.RowType == DataControlRowType.DataRow)

     {

          //*******************************************************8

          // code here. (This code given below)

          //

     }

}

单击事件分配

 LinkButton _singleClickButton = row.FindControl("lnkBtnClk") asLinkButton;

 string _jsSingleClick = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "");

 e.Row.Attributes.Add("onclick", _jsSingleClick);

用于双击事件分配

 LinkButton _dblClickButton = row.FindControl("lnkBtnDblClk") asLinkButton;

 string _jsDoubleClick = ClientScript.GetPostBackClientHyperlink(_dblClickButton, "");

 e.Row.Attributes.Add("ondblclick", _jsDoubleClick);

我们可以在行命令方法中处理这个已分配的事件，如下所示。

protected void grdClickDoubleClick_RowCommand(object sender, GridViewCommandEventArgs e)

{

     GridViewRow row = (GridViewRow)((Control)e.CommandSource).NamingContainer;

     switch (e.CommandName)

     {

          case"clk": //"clk" is command name of linkButton Row click event handler

               grdClickDoubleClick.SelectedIndex = row.RowIndex;

          break;

          case"dblClk"://"dblClk" is command name of linkButton Row Double click event handler.

               row.BackColor = System.Drawing.Color.Pink;

          break;

     }

}

如果我们要同时处理点击和双击，那么我们必须稍微更改上面的点击处理程序

 LinkButton _singleClickButton = row.FindControl("lnkBtnClk") asLinkButton;

 string _jsSingleClick = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "");



 ///We make the script as below format.

 //javascript:setTimeout("POSTBACK SCRIPT", 500)

 _jsSingleClick = _jsSingleClick.Insert(11, "setTimeout(\"");

 _jsSingleClick += "\", 500)";



 e.Row.Attributes.Add("onclick", _jsSingleClick);

然后我们可以处理行单击和双击。
