AJAX :: Find The Rating Inside A Gridview On Submit Button?

Jun 18, 2010

I have 5 questions to rate a product. These questions are in the database and I disply these questions to the customer in a GRIDVIEw. In order to make the rating easy, I give a tool like this- This tools is part of GridView in a TEMPLATE Field. A set of 5 stars will be available against each question. The user can rate each question by selecting the stars. Now, when the user clicks on the SUBMIT button, I want to receive the 'CURRENT RATING'. At present I am giving- Rating1.CurrentRating But, this doesn't give me any value because the rating tool is inside GRIDVIEW1. So, what changes should I make in Rating1.CurrentRating to receive the current rating value.

i am using this way
[Code]....

i am not able to get the selected rating value

on button submit i am using

AjaxControlToolkit.Rating rating1=(AjaxControlToolkit.Rating)row.FindControl("Rating1");

int rating =
Convert.ToInt32(rating1.CurrentRating);

It give value of first row but did not give me value of second row.

VS 2008 - Trying To Find Source Of Exception

Dec 20, 2011

My exception handler is written like so:

Code:
Try
LoggerWrite("EX - Message: " & Ex.Message.ToString, "ErrorLog")
Dim myDE As DictionaryEntry
If Ex.Data.Count > 0 Then
For Each myDE In Ex.Data
LoggerWrite(" EX DictionaryEntry: Key = " & myDE.Key.ToString & " Value = " & myDE.Value.ToString, "ErrorLog")

[code]....

The user is getting a 500 internal error occurred. What he is trying to do is create a datagrid. The error only happens when there are a lot of data used to build the grid. But why exactly is it too much data? And can I increase a buffer or set something in a config file to allow all the data? The data come from a web service.

ReportViewer Cannot Find Data Source Remotely?

Feb 12, 2010

this is the first time I have tried this so I am probably missing something that is staring me right in the face.

I have an ASP.NET page where the user fills in a request which then emails a PDF rendered from a ReportViewer instance.

It all works fine when I run it locally through the ASP.NET localhost but when I try and run it of the webserver it fails with the following message:

An error has occurred during report processing.Cannot create a connection to data source 'DataSource1'.

I can preview the report via the web based report manager via http://servername/reports which works without any problem and using the report editor in VS2005.

I suspect it is something to do with the credentials but I am at a loss. The data source is set with a username and password but this is saved within the datasource.

C# - Find The Most Efficient Way To Do Source Control In A Small Dev Environment?

May 14, 2010

I work in a group of 4 .Net developers. We rarely work on the same project at the same time but it does happen from time to time.We use TFS for source control. My most recent example is a project I just placed into production last night that included 2 WCF services and a web application front end. I worked out of a branch called "prod" because the application is brand new and has never seen the light of day. Now that the project is live, I need to branch off the prod branch for features, bugs, etc...

So what is the best way to do this?

Do I simple create a new branch and sort of archive the old branch and never use it again?

Do I branch off and then merge my branch changes back into the prod branch when I want to deploy to production?

And what about the file and assembly version. They are currently at 1.0.0.0. When do they change and why? If I fix a small bug, which number changes if any? If I add a feature, which number changes if any?

What I am looking for is what you have found to be the best way to efficiently manage source control. Most places I have worked always seem to bang heads with the source control system in on way or another and I would just like to find out what you have found that works the best.

Visual Studio :: Intellisense Can't Find The Source Files For BIN Referenced Assemblies

Mar 23, 2010

When I use Project Reference to add dependent assemblies to my C# library project, I can use the "Go To Definition" popup menu item to go to the source file of the class defined in the dependent assembly. That is one of the most useful features of VS for me. However, when I add dependent assemblies as BIN References (via the Browse tab of the Add Reference dialog), I only get the class definition generated from metadata of the dependenat assembly, not the source file.

I realize that intellisense can't find the source directory of the dependent assembly, but where can I enter the directories so intellisense would know? There is a "VC++ Directories" page in the Options->Projects and Solutions dialog, but that is only for C/C++ projects. There should be one for C# as well. The bigger mystery is when I put my project in the debugger, I can step into methods defined in the dependent assembly and see its source file. Why could the debugger find the source file but not intellisense?

I'm trying to write code that will disable submit button (or all submit buttons) on the page to avoid double postback.I thought of generating my own postback javascript function (and inject postback javascript using GetPostbackEventReference) but maybe there are some better ways to do this? Or maybe there is some other way to avoid double postbacks?

Disabled Submit Button & Javascript Error Outside Update Panel?

Jun 2, 2010

[URL]

I'm using the code the above and running into an error i can't quite figure out. Maybe its something simple or maybe it's something that can't be done. Not sure.

I created a user control (button) that references a javascript file like this:

string url = ResolveClientUrl("./Scripts/main.js");
function SubmitButton_Click(e) {
try {
var src = typeof (event) != 'undefined' ? event.srcElement : e.target;

[Code]....

The error that i am running into is this:

The buttons in the update panel work everytime without any problems. When i click a button in the update panel and then click a button outside the update panel it chockes on this line of the above javascript.

src.aspnet_onclick();

The value of aspnet_click() is 'SubmitButton_Click(e)'. This is incorrect which causes it to choke.

The value should be 'onclick(event)'

For some reason when click the button inside the update panel and then the button outside the update panel causes this javascript error but I am not sure why the aspnet_onclick() is incorrect.

Javascript - Focus On Submit Button Using JQuery When Pressing Enter In Textbox?

Nov 10, 2010

I have a page with multiple textboxes and each has a button associated with it. This works as a search 'hub', I suppose, where the user can search by ID, name etc. When entering a search term for e.g. name however, pressing enter 'clicks' the very first button on the page (ID search), causing an error if the associated textbox is empty (which it would be if someone meant to search by name). I have attempted to rectify this using JQuery, and have written the following:

$('input:text').click(function (e) {
e.preventDefault();
$(this).next('input:button').focus();
});

I'm simply using the click event so that I can monitor where focus is redirected, but eventually I would use .keypress. However, nothing happens upon clicking a textbox and I can't see for the life of me what is wrong with the JQuery. To elaborate on the problem, the .NET code used looks similar to the following throughout the page.

<tr>
<td style="width:100">Company ID</td>
<td style="margin-left:3px;">
<asp:TextBox ID="...TextBox" runat="server" Width="230px"></asp:TextBox>
</td>
<td>
<asp:Button CssClass="Button" ID="...NameSearch" Text="Search" runat="server" /></td></tr>

This is generating this (view source):

<td><input name="...TextBox" id="...TextBox" style="width: 230px;" type="text"/></td>
<td><input name="...NameSearch" class="Button" id="...NameSearch" onclick="javascript:__doPostBack('...NameSearch','')" type="button" value="Search"/></td>

Disabling Submit Button In Web Application With JavaScript Breaks BlackBerry Submission?

Apr 12, 2010

The following code is being used to disable a Submit button once it has been clicked. This works great on desktop browsers and most BlackBerry mobile browsers.

Submit.Attributes.Add("onclick", "javascript:this.disabled=true;" +
ClientScript.GetPostBackEventReference(Submit, null));

when using a BlackBerry Storm clicking the submit button causes the device to just reload the page. If I remove this code the Storm browser submits the page just fine. I need to disable the button when the browser is capable of doing so but do not want to affect browsers that are not JavaScript capable.

Web Forms :: Silverlight Media Player Change Source And Play From Javascript?

Jan 22, 2010

I am having trouble accessing an embedded Silverlight 2 media player in an aspx page from Javascript and was hoping someone might offer some insight on what's going on.

What I want to do is fire a javascript event on the client when a button is pressed to change the Silverlight media player media source and then play the newly selected file.

I found what seemed like a pretty straightforward example on the silverlight.net site that looked like this:

[Code]....

However, when I run it, I get an error "undefinedObject doesn't support this property or method".

I've confirmed that the client-side id I am using is correct, and I have tried using document.GetElementByID in place of $find (which is what I use elsewhere on the site successfully; my javascript kung fu is weak and I'm not precisely sure what the difference
might be) but it still doesn't work. It all seems like it should work as it was presented in the example, but I only get that error.
