没有从gridview中的CommandArgument获取正确的值 [英] not getting correct value from CommandArgument in gridview

问题描述

Hello all



i我试图使用CommandArgument从我的GridView获取ID值，但是当它返回行索引值而不是ID值时

< asp：TemplateField HeaderText =   HeaderStyle-Horizo​​ntalAlign =  中心 >  
< ItemTemplate> 
< asp：ImageButton ID =   imgbtnDelete CommandName =   Delete1 CommandArgument = ' <％＃Eval（VisID）％>' runat =   server ImageUrl =   images / button_delete.png /> 
 < /   ItemTemplate  >  
< HeaderStyle Horizo​​ntalAlign =  中心 /> 
 < /   asp：TemplateField  >  
 

这是我的C＃代码：

  protected   void  grdAppuser_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
  if （e.Row.RowType == DataControlRowType.DataRow） 
 {
 ImageButton delBtn =（ImageButton）e.Row.FindControl（  imgbtnDelete）; 
 
 delBtn.Attributes.Add（  OnClick， 返回确认（'您确定要删除'）;）; 
 
 e.Row.Attributes [  onclick] = ClientScript.GetPostBackClientHyperlink （ this  .grdAppuser， 选择$ + e.Row.RowIndex）; 
} 
 
 
 受保护  void  grdAppuser_RowCommand（< span class =code-keyword> object  sender，GridViewCommandEventArgs e）
 {
 System.Threading.Thread.CurrentThread.CurrentCulture =  new  System.Globalization.CultureInfo（  en-US）; 
 
 尝试 
 {
  switch （e。 CommandName）
 {
  case （  Delete1）：
 
  string  id = Convert.ToString（e.CommandArgument）;  //  这里的问题此行返回行索引而不是ID  
} 

所以我说e.CommandArgument返回行索引而不是ID值。



请帮助



谢谢

解决方案

+ e.Row.RowIndex） ;
}


受保护 void grdAppuser_RowCommand（ object sender，GridViewCommandEventArgs e）
{
System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo（ en-US）;

尝试
{
开关（e.CommandName）
{
case （ Delete1）：

string id = Convert.ToString（e.CommandArgument）; // 这里的问题此行返回行索引而不是ID
}

所以我说e.CommandArgument返回行索引而不是ID值。

首先，从代码中删除以下行

 e.Row.Attributes [  onclick] = ClientScript.GetPostBackClientHyperlink（ this  .grdAppuser， 选择

+ e.Row.RowIndex）;

System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo（ en-US）;

然后添加以下你的gridView aspx事件

 <   asp：gridview     id   =  grdAppuser    runat   =  server    autogeneratecolumns   =  false    xmlns：asp   = ＃unknown >  
 OnRowCommand =grdAppuser_RowCommand OnRowDataBound =grdAppuser_RowDataBoundWidth =90％> 
 
 
 <   asp：imagebutton     id   =  imgbtnDelete    commandname   =  Delete1    commandargument   =  <％ #Eval（  VisID）％>    runat   =  server    imageurl   =  images / button_delete.png    /  >  
 <   / asp：gridview  >  

然后添加在你的行命令事件中，你肯定会得到 e.CommandArgument 值

< br $> b $ b

 受保护  void  grdAppuser_RowCommand（ object  sender，GridViewCommandEventArgs e）
 {
  switch （ e.CommandName）
 {
  case （  Delete1）：
  string  id = Convert.ToString（e.CommandArgument）; 
} 
} 

希望这对您有用。

Hello all

i am trying to get ID value from my GridView using CommandArgument, but when it is return the row index value instead of ID value

<asp:TemplateField HeaderText="           " HeaderStyle-HorizontalAlign="Center">
       <ItemTemplate>
                     <asp:ImageButton ID="imgbtnDelete" CommandName="Delete1"                          CommandArgument='<%# Eval("VisID") %>' runat="server" ImageUrl="images/button_delete.png"/>
       </ItemTemplate>
       <HeaderStyle HorizontalAlign="Center" />
</asp:TemplateField>

and this is my C# code:

protected void grdAppuser_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ImageButton delBtn = (ImageButton)e.Row.FindControl("imgbtnDelete");

            delBtn.Attributes.Add("OnClick", "return confirm('Are you sure you want to delete');");

            e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.grdAppuser, "Select$" + e.Row.RowIndex);
        }


protected void grdAppuser_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");

        try
        {
            switch (e.CommandName)
            {
                case ("Delete1"):
                    
                    string id = Convert.ToString(e.CommandArgument); // the problem here this line return row index instead of ID
     }

so as i said the e.CommandArgument return row index instead of ID value.

please help

thank you

" + e.Row.RowIndex); } protected void grdAppuser_RowCommand(object sender, GridViewCommandEventArgs e) { System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US"); try { switch (e.CommandName) { case ("Delete1"): string id = Convert.ToString(e.CommandArgument); // the problem here this line return row index instead of ID }

so as i said the e.CommandArgument return row index instead of ID value.

First of all, remove following lines from your code

e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.grdAppuser, "Select

" + e.Row.RowIndex); System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");

Then Add following events to your gridView aspx

<asp:gridview id="grdAppuser" runat="server" autogeneratecolumns="false" xmlns:asp="#unknown">
OnRowCommand="grdAppuser_RowCommand" OnRowDataBound="grdAppuser_RowDataBound" Width="90%">


<asp:imagebutton id="imgbtnDelete" commandname="Delete1" commandargument="<%#Eval("VisID")%>" runat="server" imageurl="images/button_delete.png" />
</asp:gridview>

Then add this in your Row Command event, you will surely get e.CommandArgument value

protected void grdAppuser_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        switch (e.CommandName)
            {
                case ("Delete1"):                    
                    string id = Convert.ToString(e.CommandArgument); 
            }
     }

Hope this will work for you.
