How do I stop the postback from a asp button? I want to do some validation on
the client side when a button is pressed and decide whether to post back to
the server or not.

Thanks
Hari

Hi Hari

you can do this by adding small attribute(JavaScript function) to Button.
on form load event of code behind file

<Your Button Name>.Attributes.Add("OnClick", "return confirm('Continue?');");

or

<asp:Button ID="btnSample" runat="server" Text="View Detail"
OnClientClick="return confirm('Continue?');" />

hope this Help

Thanks..

Hi TRK@UK,

Thanks for the response, this is working fine as expected.

I tried something more...

In Page Load
--
Object objAjax = Request.QueryString["from"];
        if (objAjax != null)
        {
            Response.Clear();
            Response.Write("1");
            Response.End();
        }

        //Button1.Attributes.Add("OnClick", " if(TextBox1.value=='hari'){return true}else{return false};");
        Button1.Attributes.Add("OnClick", " var finalval = chkText(); if(finalval == false){return false;}"); 

---

<script language="javascript" type="text/javascript">
    var XmlHttp;   
    function chkText()
    {
      try
        {
           XmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
        }
        catch(e)
        {
           try
           {
              XmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
           }
           catch(e1)
           {
              XmlHttp = null;
           }
        }
            //Creating object of XMLHTTP in Mozilla and Safari
        if(!XmlHttp && typeof XMLHttpRequest != "undefined")
        {
           XmlHttp = new XMLHttpRequest();
        }           
        if(XmlHttp)
        {
              try
              {
                XmlHttp.onreadystatechange = HandleResponse;
                XmlHttp.open("POST", "CallingServerFunctionUsingAjax.aspx?from=Ajax",true);
                XmlHttp.send(null);                
                if(XmlHttp.readyState==1)
                {
                    return false;
                }
              }
           catch(e2)
           {
              alert(e2);
           }
        }      
}


function HandleResponse()
    {
      try
      {                 
       if(XmlHttp.readyState == 4)
        {
          if(XmlHttp.status == 200)   
            {
                 var retval=XmlHttp.responseText;                                                                                                 
                  switch(retval)
                  {                      
                      case "1":                                                                                      
                                 return false;
                                  break;                                                     
                                 
                      default:                                   
                                 break;
                  }
             }
           else
             {
                alert("Problem with saving data");
             }
        }   
    }
    catch(e)
    {
      alert("Error");
    }
  }  
    
    </script>

But the function chkText() is not acepting the return value....
What is the problem.........

Thanks
Hari

Alternatively, if you're using 2.0, the buttons expose an OnClientClick attribute which fires (on the client side obviusly, so you'll need to give it a javascript function) before OnClick...to stop OnClick, return false from OnClientClick

I have a repeater displaying repeated rows, trying to figure a way to keep the first appearence and remove the next but it is not working

how can i detect a first ocurrence of a record and add a e.Item.visible = false here?

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

{

if (Convert.ToString(((Label)e.Item.FindControl("itemselected")).Text) != "")

{

((CheckBox)e.Item.FindControl("selectitem")).Checked = true;

}

//fstk.STOCK_ID as fsselected

if (Convert.ToString(((Label)e.Item.FindControl("fsselected")).Text) != "")

{

((CheckBox)e.Item.FindControl("selectitem")).Checked = true;

((CheckBox)e.Item.FindControl("selectitem")).Enabled = false;

}

Hi
Installing Ajax toolkit itself not enough to see Controls on your IDE.

To See Ajax Toolkit in your ToolBox Rightclick on toolbox and chooseItems then Browse add
Reference to "AjaxControlToolkit.dll"

This DLL Avilable @ \SampleWebSite\Bin\AjaxControlToolkit.dll

you will see all Ajax cotrols in your toolbox.Drag n drop controls you wish to use.

Aspx, cs, config files.

If you have doubt on security then you can go for publish website option. That will generate dll's and you can upload that along with the ASPX files.

Hello,
if your DataGrid name is dgGrid then try the following code

System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw =
new System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
dgGrid.DataSource = dsExport;

// Get the HTML for the control.
dgGrid.HeaderStyle.Font.Bold = true;
dgGrid.DataBind();
dgGrid.RenderControl(hw);

// Write the HTML back to the browser.
Response.ContentType = "application/vnd.ms-excel";
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
