I define the datasource in my c# code and I have a submit button which takes the value of the radiobuttonlist
asp:RadioButtonList ID="RadioPaidIdList" runat="server" DataValueField ="Label" DataTextField = "Label"
First time i click submit it returns an empty value. And next time i select a radiolist and click submit it returns a proper value.
With script below, request to the server always sends empty string (even if value is not emtpty), where the data line is:
data: "{ 'folderName': '" + $(this).val() + "' }"
The html element under investigation is this:
<asp:TextBox id="searcher" runat="server" ClientIDMode="Static" CssClass="classificationFolder" />
Script is:
<script type="text/javascript">
$(document).ready(function () {
$(".classificationFolder").each(function () {
[Code]....
The reason that I select elements by css class selector ($(".classificationFolder")) is that, this control is a user control and used in the same page more than once. That is why I'm not using $("#searcher").
I tested the code In IE8 and Chrome 8.0.552.28 beta. This issue is arising in both of the browsers.
On the other hand, request is sent to the server, client received response successfuly and response is processed on the client.
This is completely frustrating and probably embarrassing as well. A while back I posted a similar question and resolved the issue. [URL]...scope_identity The program has been working ever since, until yesterday when as it turns out SCOPE_IDENTITY() started returning an empty string even though a record is being inserted. I am not sure what has changed since the fateful day.
[Code]...
I am hoping that there is something I am just not seeing here. A lot of the information I have seen thus far indicates that there are problems with SCOPE_IDENTITY() but most of those are related to inserting multiple records. As you can see this should be fairly straight forward. The thing that really has got my goat is that it used to work and now it doesn't. If someone could take a look at the above code and comment on any anomalies it would be great. Also I have heard suggestions for switching to ADO.NET and it is beginning to look a lot more attractive every day. But I have a ways to go before making the switch so it is SqlDataSources for now
I have developed a web application 3 months ago to show facebook users by searching username. To access facebook, I have downloaded facebook dll and got application key, and secret key from facebook. My web application was working fine and displaying records from facebook. yesterday onwards, my application is not working fine. I could not get response when I search by name. I have tested the fql in the facebook testAPI tool online. That time i can get response. but the same fql i used in my appliation but it could not get response from facebook when I search by name. If i search by uid i can get response from facebook. here is my code.
facebook.Components.FacebookService fb = new FacebookService();
fb.ApplicationKey = "bfeefa69afdfe81975f0d6136ace3009";
fb.Secret = "9b672d682e1d8befd06382953fc2615b";
fb.IsDesktopApplication = false;
//the below fql gives response as xml.
//select name, profile_url from user where uid = '1730923544' -I can get response for this fql.
//the below fql does not give response as xml. But it gives empty string.
//the below fql does gives us response as xml when i try in facebook testAPI.
//select name, profile_url from user where name = 'Suresh Rajan' -I couldn't get response for this fql.
string s = fb.fql.query("select name, pic_square, profile_url from user where name = 'Suresh Rajan'");
if (String.IsNullOrEmpty(str1))
Response.Write("Empty Response");
else
Response.Write(str1 + " ");
how to search by name in facebook fql.
I am experiencing the "Input string was not in a correct format." error and I have no clue how to fix it.
I have a radiobuttonlist and a submit button, the radiobuttonlist is dynamically bounded to a datasource. when user clicks on the submit button, I am trying to retrieve the selected value in the radiobuttonlist, but somehow the radiobbuttonlist selectedvalue is null. How to retrieve the selectedvalue for the radiobuttonlist?
The aspx form code is as below:[Code]....
aspx.cs code: [Code]....
The form displays the radiobuttonlist listitem value without problem. However, the rdChoice.SelectedValue is null.
I've two RadioButtonLists which pulls "fullName" and displays, the idea is for the user to select from RadioButtonList1 and RadioButtonList2 then submit the data.
If there is already values assigned from sql then there should be a selectedvalue for both controls. But I can't seem to get the controls to assign the selectedvalues.
I've a SqlDataSource, 2 RadioButtonLists and some code binding it:
[Code]....
Also when I go to select just one record from RadioButtonList and submit the data, it returns errors because it sees it as submitting null values.
rbl.DataSource = ds;
View 8 RepliesI have a FormView with an EditItemTemplate. In the EditItemTemplate I have a RadioButtonList. I want to populate the selected button from the database. My code looks like this (simplified):
[Code]....
The stored procedure usp_GetOrderDetails returns a char(1) column called "side" which can have values of 'B' or 'S'. If it's a B or an S I want to select the correct item in the RadioButtonList, radSide. Is this possible? I've done it for my Text boxes and dropDownLists on the same form OK, I just can't figure out the RadioButtonList.
I have Gridview inside that i have RadioButtonList,Which is working perfectly. It also bind correctly.
Problem is when user navigate page,the value which was slected in previous page is not apper again.
Gridview is enabled with paging.
I want to save data on SUBMIT button which is outside gridview. So when user clicks this button it should get ALL selectedvalue of radiobuttonlist inside gridview INCLUDING paging and save it to database.
I have tried following code on Button_Click but its not working properly.

There are two dropdowns in my ASP.NET form. The second dropdown is dependent on the first dropdown - the second onedoes not have the item selected in the first one. My problems is that the selectedValue for the second dropdown is always empty after load event. I tried to set the selectedIndex to be 0 before access selectedValue property in the page load event, but it is still empty. What I want is to get the first item of the second dropdown as the default value.

I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes.

But i want a solution while maintaining the bound fields ,if any.
View 2 RepliesI have a class library which has my LINQ doc in it. I added a stored procedure and I get the following in my .dbml.layout :

I include a reference to the dll of the class library to my web project and I get an error about value being returned as int where I am trying to put contents into a datalist or similar.
Code in class that calls this SP :

So I switched code to the following in my dbml.layout document :
[Function(Name="dbo.sp_newsSearch")]public IEnumerable<news_search_result> sp_newsSearch([Parameter(DbType="VarChar(200)")] string searchVal){IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), searchVal);return ((IEnumerable<news_search_result>)(result.ReturnValue));}
And included the following in an external file news_search_result.cs
[Code]....
But now I just get nothing returned. Is this wrong way of calling a SP via LINQ? or have I just put the wrong return type on my LINQ class?

I have two sub routines that I've created to pull in my Membership user roles and assign the value/name of that role to the value of a cookie.
My first subroutine looks like this
[Code]....
At this point, role ID is a 1-dimentional array which is not acceptable for a cookie's value (it must be a string), but in Debug mode, I can see that the array does contain the correct roleID value. In my 2nd subroutine I change the value from array to string for no other reason than that it gives me an opportunity to see that the value of CookieValue() before it is converted does have the correct roleID.
[Code]....
Even though it still shows that string as having the correct value, it returns the object "System.String[]"
[Code]....
returns the error: The parameter 'username' must not be empty.Parameter name: usernameI want to check if a user is logged. If not logged in redirect to loginerror.aspx.

View 7 RepliesI am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet. If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown. A test program in windows form is also working fine regardless of how many rows.
