Hello
I try to use an Imagebutton instead of a LinkButton in my gridview to select and to delete a specific row but when using the asp.net application and press the image it will give this error:
"Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true"> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
"
Please help
And tahnks in advance

Hi All,
I hope all are doing good.Anyway
I need your help in calling webservice. I have one page with Address fields like address,city,State ans zipcode
Now i have to call a service and have to pass Address values to the service. Again before calling service i have to Validate these fields at server side if all things are right then call should made to service. After calling service I need to display dynamic text depending on the service result.
Now the question is which is better way to call the service
1. using Ajax and call the service from the function present at server
2.Is there any way to call service from JQuey but how to Validate my form fields (Custom Validation is at server no client side validation).
3. Can i use Page Methods for this but i need to update some fields on the page (Validation).
Any Ideas ?
Note: I can't make client side validation as i need to check State and zipcode value, User should provide correct zipcode for the state he has selected

Go with server side calling
You can use Ajax also if it is already present on the Page then only use it .
As u can't perform validation at client side there is no meaning in calling service using javascript

Hi All,

javascript:void(window.close())
Put that in the PostBackUrl of the asp.net button
The answers posted by me are suggestions only and cannot be used in anyway against me.

Thanks... .netman
but it is still not working.

<asp:button id="Button1" runat="server" text="Button" postbackurl="javascript:void(window.close())" xmlns:asp="#unknown">

d'kng wrote: window.open('','_parent','');
What is that ?
you need to close the browser on button click
Register this javascript onclick event of button at server side
ButtonID.Attributes.Add("onclick", "javascript:closeWindow();");
and javascript function is
<script language="javascript" type="text/javascript">
function closeWindow() {
window.close();
}
</script>
if you don't want to show any confirm message before closing then write
window.opener = self;window.open('','_parent','');window.close();
Thanks and Regards

In the user control I have
<asp:imagebutton id="ImageButtonBanner" runat="server" xmlns:asp="#unknown" />
and in the user control Page_Load event I set:
this.ImageButtonBanner.ImageUrl= "~/naitaBannerit.aspx?pictureId=0";
In the naitaBannerit.aspx page I read picture from databse VARBINARY(MAX) field with additional info like:
string pildiID = Request.QueryString["pictureId"].ToString();<br />
SqlConnection myConnection = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["connString"].ToString());<br />
myConnection.Open();<br />
SqlCommand myCommand = new SqlCommand("dbo.AD_PICTURE_KUIDO_S", myConnection);<br />
myCommand.CommandType = CommandType.StoredProcedure;<br />
myCommand.Parameters.AddWithValue("@pictureId", Convert.ToInt32(pildiID));<br />
SqlDataReader rd= myCommand.ExecuteReader();<br />
while (rd.Read())<br />
{<br />
Response.ContentType = rd["TYYP"].ToString().Trim();<br />
byte[] imageContent = (byte[])((rd["PICTURE"]));
//and I also add additional info from database to Response.AppendHeader
Response.AppendHeader("laius", rd["width"].ToString());<br />
Response.AppendHeader("korgus", rd["height"].ToString());<br />
Response.AppendHeader("reklaamilink", rd["LINK"].ToString().Trim());<br />
Response.BinaryWrite(imageContent);<br />
break;<br />
}<br />
rd.Close();
Is it possible to use these Response.AppendHeader with asp:ImageButton control
like
this.ImageButtonBanner.PostBackUrl = HttpContext.Current.Request.Headers["reklaamilink"].ToString();
or how to capture ImageButton call to/from ImageUrl ?

|

Ah, in your subject it says autohide. You could put the treeview control inside the sliding menu.

Hi all,
I had my application running very well till date on the server for last 4-5 months. I added the AJAX functionality some 3-4 months back. When i initially encountered this problem , i learnt that some Ajax related stuff needs to be added in web.config.
when i added that stuff it all started working. No problems it gave then. But suddenly today it started giving the same prob. I haven`t changed anything, so why does this problem arise again?????
any ideas how to solve this problem????
When you fail to plan, you are planning to fail.

This doesnt make sense that the problem could just arise out of nothing unless you have made a change to the way the application works or you if you have made a change to the framework on the server. What ajax control does it arise out of and what exactly happens?

Make sure that your web.config is having all tags required for AJAX Asynchronous calls
