View 4 Replies need to send a byte array from javascript into a c# page method. The int and string variables work fine, but when I step through the c# code, the "object" which was the byte array is null, even though I checked to see if it had a value in JS.
var byteArrayObj = GetBinaryDataFromFile(filePath);
var tranAttachmentName = filePath.replace(/^.*\/, '');
PageMethods.AddFileToTran(tranId, tranAttachmentName, byteArrayObj, RefreshPage, onTimeout, onError);

I have the following Silverlight control defined:
[Code]....
I have exposed the following method in my Silverlight control (Page.xaml.cs) to be accessible to Javascript:
[ScriptableMember]
public bool HasPendingUpdates()
{
return btnSave.IsEnabled;
}
I then have a Javascript test function in my aspx page that is trying to do something with it:
var imageViewer = $("#objImageViewer")[0];
if (imageViewer.Content.Page.HasPendingUpdates())
{
alert("Pending Changes Exist!");
}
else
{
alert("NO Pending Changes Exist!");
}
Problem is that it fails after the Content object. I have tested the following:
var imageViewer = $("#objImageViewer")[0];
imageViewer // Valid
imageViewer.Content // Valid
imageViewer.Content.Page // Invalid
imageViewer.Content.HasPendingUpdates() // Invalid
So I am not sure what I am doing wrong. How do I get to the function within Content?
I am using IE8, Silverlight 3, ASP.NET. The silverlight control is created with the object tag as I don't think the control is an option in Silverlight 3+.
I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
<asp:Content ID="Content6" ContentPlaceHolderID="Mainpage" Runat="Server">
<script src="path1" type="text/javascript"></script>
<script src="path2" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
</script>
</asp:Content>
On running the website I get the following runtime error in visual studio: Microsoft JScript runtime error: 'this.node' is null or not an object and it point to some function inside the JavaScript like this.node.onload=function(){..............//I am not a java guy so do not know much about this Where am I going wrong? Why does the site compile correctly but throw this runtime error? I also tried inserting this java code inside the master file in the <head>, but same error.
How would I pass an Object or Array to a function using the ICallBackEventHandler (RaisCallbackEvent)? It allows for a string argument only, if you change it to another datatype it error out. Sample Below...

The first commented line below is working with a hardcoded ApplicantId, and all I need is to make it work by passing the current ApplicantId column on the same gridrow.
I've tried for many days now, and something like the second commented line does not work for me.
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
DataKeyNames="ApplicantID" >
<Columns>
<asp:TemplateField HeaderText="Select">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<!-- works -->
<asp:HyperLinkField NavigateUrl="javascript:popUp(3)" Text="Select" Target="_parent"/>
<!-- doesn't work -->
<asp:HyperLinkField NavigateUrl='"javascript:popUp("<%# + DataBinder.Eval(GridView1.DataItem,"ApplicantId") %> + ")"' Text="View" />
</Columns>
</asp:GridView>
I am trying to call a javascript function which will set forecolor and backcolor of a control when the control is loaded
But this function is not raising.
[Code]....
I have the following:
<EditItemTemplate>
<asp:Button ID="wrqst_need_ind_btn" runat="server" Text = "Create WR"
onClientClick="javascript:popUp('popup_createWR.aspx')"
CommandArgument='<%# Eval("dvc_nm") + "|" + Eval("data_orgtn_yr") %>'/>
</EditItemTemplate>
I want to pass in as two additional params the Eval("dvc_nm") and Eval("data_orgtn_yr") to the popup function.
UPDATE:
I tried by removing the single quotes from insode the <% %> tags. Which gave me this:
onClientClick='<%# "javascript:popUp(popup_createWR.aspx," + Eval("dvc_nm") + "," + Eval("data_orgtn_yr") + ")" %>'
which complied, but when I clicked the button I did not get a pop up, the page just posted back and reloaded and said errors on page, but no popup...
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?
View 1 RepliesI have a button inside my <ItemTemplate> in GridView and I want to call a javascript function on the OnClientClick of that button passing the DataItem value as a parameter of the javascript function
[code]....
If I will not put a parameter in CreateEditAddess() this works well but I need the parameter.
I know I can put the OnClientClick event value in OnRowDataBound event of the gridview but I don't want to put it in CodeBehind. It seems like the server tag is not parsed correctly.
I want to create one web application in which I will click on cell of a gridview after that one javascript file will be called that will again call a asp.net web page

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.
