This may be a basic question. I know __doPostback() function accepts 2 arguments, eventtarget and eventargs. eventtarget is used to identify the control that causes postback. Then what is the use of eventargs in doPostback function?? I saw the _doPostback function always set the __EVENTARGUMENT hidden field to nothing for any postbacks caused thro controls with even autopostback to true or a control like linkButton.
View 2 RepliesI have a form with multiple dropdownlist and each list has onselectedindexchanged defined.
<asp:DropDownList ID="SPR" runat="server" OnSelectedIndexChanged="Reload_OnSelectedIndexChanged" AutoPostBack="true">
<asp:ListItem Text="1 day" Value="1:D"></asp:ListItem>
<asp:ListItem Text="5 days" Value="5:D"></asp:ListItem>
<asp:ListItem Text="1 month" Value="1:M"></asp:ListItem>
<asp:ListItem Text="3 months" Value="3:M"></asp:ListItem>
<asp:ListItem Text="6 months" Value="6:M"></asp:ListItem>
<asp:ListItem Text="1 year" Value="1:Y"></asp:ListItem>
<asp:ListItem Text="2 years" Value="2:Y"></asp:ListItem>
</asp:DropDownList>
So when I run the page I expect to receive the postbackcode and the select code with the onchange property defined.
When I invoke the pages in Explorer, Safari or Chrome everything works fine but in Firefox the __doPostBack function and the onchange property in the select tags are not defined. Why is that?
I have a web forms page with a button that involkes a __doPostBack callback to the page. I would like to invoke this manually - by "manually" I mean from outside the webpage, for example by using wget.
View 3 RepliesHere is my simple markup, I hope its understandable as to what I am trying to do
<form id="form1" runat="server">
I have Sub that requires EventArgs as below.
Sub Testing(ByVal sender As Object, ByVal e As EventArgs)
If I want to call the Sub from PageLoad event, I wrote like this Testing(nothing,nothing)
Then, in the Sub, I would like to check If Argment is Nothing or not
Dim testID As String
If (CType(sender, LinkButton).CommandArgument) = Nothing
testID=Request.QuerySting("myID")
ELSE
testID=(CType(sender, LinkButton).CommandArgument).ToString
End If
I get Null error at if statement (If (CType(sender, LinkButton).CommandArgument) = Nothing)
what I can replace the bold line with to get it working with EventArgs e? I copied this code from a button function with CommandEventArgs e.
protected void btnNextStep_Click(object sender, EventArgs e)
{
if (cboxShippingSelect.Checked == true)
[Code]....
I have two buttons in a list view that adjust the position of that item, basically, moves it up or moves it down. Both buttons have the CommandName="Select" so I need to know if their ID is somewhere in the EventArgs so I can tell if the Up or the Down button was pressed.This is my temporary sol'n, maybe it'll give you a better idea of what I mean to do.int s;
public void iBtnUp_Click( object sender, EventArgs e )
{
s = 1;
[code]...
protected void ok_Click(object sender, EventArgs e)
View 2 RepliesI have a server side control RaiseCallbackEvent implemented. I want to intercept raisecallbackevent after it finished executing RaiseCallbackEvent method in the serverside and want to execute other code in the .aspx template.
1) Is there any pagelife cycle event that fires after RaiseCallbackEvent?
2) Is there any way to fire jquery function after RaiseCallbackEvent from client side?
Argh.. I've run into thei before,but can't remember how I solved it.I have a gridview with a button in a template field.I've added an event to the button,but am getting the dreaded 'RowIndex' is not a member of 'System.EventArgs' error.
I'm trying to grab the value of a label in the gridview for the row that is selected when the button is clicked.Should I be using something other than e.RowIndex?

I am a beginner ASP.NET C# developer and have a question about a concept. When I declare a function, I have something generic like:
public void sample_function(object sender, EventArgs e)
{
//function code
}
What I want to know is what does the "object sender and EventArgs e" stand for? How can I use these?
Protected Sub FormView1_ItemCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewCommandEventArgs) Handles FormView1.ItemCreated
Causes Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.FormViewCommandEventArgs'.
The program (asp.net/vb) works fine with FormView1_ItemCommand and FormView1_ItemInserted events but strangely objects to FormView1_ItemCreated. Is it only a VC# event?
I have this import function which can be changed by the client in his desired way.Now I want to code such that if the client tries to import his own data on the page and doesnot give the tags in the order mentioned below his import function should be stopped.
It shouldn't make any changes unless the tags are in the right format because the problem now is if the tags are not in the right format when client changes then its importing over the existing files and directing to an error page which I dont want it should simply stop the import function if they are nt in the order.the code for this function is below

I would like to write a function to reuse some functionality that I repeat over and over...
For example:

What's changing, in every field, is only the lambda function to get the current field to edit (Name, City, Address, etc...).
What is the best method? Or better: is there ANY method to extract a generic function?

I need to create something which is like an Add friend function in my website which works like this:
1) User types in name of the person he wants to search in the search field and clicks enter
2) on the same page, the search result will come out with an "add friend" button beside every name
3) when the user clicks the "add friend" button, he will be brought to another page (or pop up with a message box?) with a text message field to send to the friend, and a submit button to submit the friend request.
4) over at the Friend's page, he will be able to view the add friend request and decide whether to accept or deny the friend request.
Take the following scenario. I have multiple ASPX pages. Login, Logout, Main, Messages, etc... They all inherit from System.Web.UI.Page of course. For all the pages, I want to override the Render method from the Page class. I could easily copy and paste the same code into each page like so:
protected override void Render(HtmlTextWriter writer)
{
//Code Logic Here
}
But if I had many pages, lets say 20, maintaining the code in each page could get very time consuming and error prone.That made me think a bit and I thought okay lets try this...override the function in each page but call a static function. That way changing the static function would result in a change for every page.Which works fine... But its not really nice and clean, having to override like that on every single page.

When 'return false' is fired, I'm assuming that the function is stopped at that point and there's no need for exit fors and things like that?
I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript functionIn order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there.
Protected Overrides Sub AddAttributesToRender(ByVal writer As HtmlTextWriter)
MyBase.AddAttributesToRender(writer)
If MyBase.RenderUplevel Then
Dim clientID As String = Me.ClientID

I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:
<input type="image" name="ibSubmit1" id="ibSubmit1" src="button-green-submit.gif" onclick="showProgress1();WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ibSubmit1", "", true, "Group1", "", false, false))" style="border-width:0px;" />
I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.
Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.
NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.
Here is the code I tried to replace the onclick event handler (not working):
$('[onclick*=WebForm_DoPostBackWithOptions]').each(function() {
var txt = this.onclick;
txt = txt + '';
txt = txt.replace('WebForm_DoPostBackWithOptions','ml_DoPostBackWithOptions');
this.onclick = eval(txt);
});
Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.
I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...
Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.
