Web Forms :: Use String Variable Before Assigning Value

Aug 15, 2010

I have a page the retieves transaction data from PayPal. The data is retrieved as a string of text. I need to break down the string and save parts of it to my database. I have justed a plain string in my test to see if my code works. I have converted some working VB code into C# but I am getting the errors when trying to Response.Write the different parts. The Error message says that I am trying to use the string variable before I have assigned a value to it.

Web Forms :: Assigning Value To Variable On A Page Dynamically And Pass To Control

Apr 11, 2010

Generally I want to pass string result of some control to other control or htm tag like without using specific classes in my ASPX page, only my control and what asp gives:

<a href="<MyControls:MyContr Param="Tech"/>">my link</a>

but this doesnt work - href is not executed, server treats it literally <MyControls:MyContr Param="Tech"/> so I would like to know it is possible to do it like in JSP pages:

- pass <MyControls:MyContr Param="Tech"/> to some variable $myVariable
- pass $myVariable to href like <a href="$myVariable" ?

Dynamically Assigning Which Variable In Vb.net Code Behind?

Mar 4, 2010

I'm looking at a routine that returns a variable name and value in two fields from a table, the intent is to then assign the value to the correct variable.

in C# the statement is

Session[dr["SessionKey"].ToString()] = dr["SessionValue"].ToString();

My code is unfortunately VB. I'm having problems with the first half of the equation - setting the variable name in VB.

SQL Server :: Stored Proc & Assigning Its Return Parameter Value To A Variable

Aug 1, 2010

I have a stored proc. that returns the USL & LSL values for each of the 8 different Metrics. say, Defect Density (Upper Specification Limit) USL = 0.30 & Defect Density (Lower Specification Limit_ LSL = 0.05). Simillarly for 8 different Metrics. Why I need these Spec. Limits ?...Because I want o compare my project's Metrics Value displayed in the Grid View with the corresponding USL & LSL value of the same Metrics. IF Metrics Value is outside of USL & LSL Then I want to Mark the Metrics in Red Color.

Forms Data Controls :: ClientIDRowIDSuffix - Assigning Value - Can't Convert Type String

Nov 30, 2010

I've been successful in creating GridView controls programically using c#. I'd like to take advantage of using the clientmode=predicatable but I can't resolve setting the ClientIDRowSuffix value. Below is a code snippet:

public void GenerateView(int fileno, string GridType, GridView dataView)
{
object ctrl = FindControl("pnlForm");
System.Web.UI.WebControls.Panel ctrlPanel = (System.Web.UI.WebControls.Panel)ctrl;
dataView.Width = 640;
dataView.ForeColor = System.Drawing.Color.Black;
dataView.BackColor = System.Drawing.Color.Beige;
dataView.AutoGenerateColumns = false;
dataView.Caption = "<B> indicate your selection by typing Add of Delete in the Action box below</B>";
//Resulted in the following error
// Cannot implicitly convert type 'string' to 'string[]
// dataView.ClientIDRowSuffix = "CTR_SEQ";
// I also tried casting it
// CS0030: Cannot convert type 'string' to 'string[]'...........................................

Jquery - Assigning Event From String

Mar 17, 2011

I'm using ASP.net and it creates a pager for a gridview that has the following HTML:

<td><a href="javascript:__doPostBack(.....)" class="MyLink">pagenumber</a></td>

The problem is that when the user clicks on the cell but not the actual content of the cell, the script doesn't trigger because it's not linked to the whole cell. So I'm writing a small script to extract the link and assign its value to a click event handler for each cell. This is what I have so far:

$('.MyLink').each(function () {
var TheLink = $(this).attr('href');
var CellContent = $(this).html();
// alert(CellContent);
var LinkExtract = TheLink.split(":");
//alert(LinkExtract[1]);
var PagerCell = $(this).parent();
$(PagerCell).click(function () { LinkExtract[1]; }); //problem here
$(PagerCell).html('');
$(PagerCell).html(CellContent);
});

Both alerts return the expected content. However, the click event doesn't work.

Being completely new to this, I am confronted by the issue of my site having three different roles that new members could fall into, but am unsure about how to assign each a role. I can't imagine having to go through the process manually if I have thousands of members.

Web Forms :: Trying To Pass A String Variable As A Parameter To The Document.getElementByID Function

Jan 17, 2011

I have a label "lbl1" that I am trying to locate in a content page from the Master page. I want to do it dynamically so I am trying to pass the name of the control (which in this case is lbl1) through as a parameter. I don't get an error, it just doesn't work. If I do an alert to see what the string "temp" looks like, it is correct, but iit seems as if Javascript ignores it. I believe it has something to do with the '<%= not being interpreted correctly by the browser&nbsp; I'm sure it is a simple solution, but I can't figure it out!

I have a page with some datasources in it. I am doing reenginering of the page itself and would like to split some parts of the page in several user controls. In my code I have an ObjectDataSource object with the following params

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
TypeName="DataSetTableAdapters.PhotosTableAdapter"
SelectMethod="GetPhotosForAlbum">
<SelectParameters>
<asp:ControlParameter Name="albumID" ControlID="txtAlbumID" Type="Int32"/>
</SelectParameters>
</asp:ObjectDataSource>

This piece of code automatically bind the hidden field "txtAlbumId" to the datasource. In my revision this datasource should be moved to a user control. What is the best way to handle a scenario like this?

Forms Data Controls :: Use A Query String Variable Created On The Fly To Populate A Child Webpage?

Feb 22, 2010

I have developed the below web page which has an asp.net 3.5 listview control as it's frontend and an sql server db as it's backend.

[URL]

The first row on the web page is the inserting row. What I am hoping to achieve is that when the user enters their appropriate data they click the "Next" button to assign this dataset with it's own identity ID (customer_id) value within my database (this works perfectly), at the same time on the fly I want to use this customer_id as a query string variable to populate a child page (customerTrades.aspx) in order to pin further data to this identity. Currently I am attempting to use the below code within the iteminserted event of my listview control but I receive the error: "object reference not set to the instance of an object"??

protected void lvTrustAccounts_ItemInserted(object sender,
ListViewInsertedEventArgs e)
{
string customerID = e.Values["customer_id"].ToString();
Response.Redirect("http://www.tradeselector.co.uk/customerTrades.aspx?customer_id="
+ customerID + "");
}

Is this because the child page cannot find the customer_id variable being passed through the query string? Because it's not actually created yet? Am I using the wrong listview event? How can I achieve what I am looking for?

I must also mention that I'm using a linqdatasource to insert my data on runtime into my database. However, I am using the listview iteminserting event to insert my frontend dropdownlist selected values, code below:

protected void lvTrustAccounts_ItemInserting(object sender,
ListViewInsertEventArgs e)
{
e.Values["customer_created_date"]
= DateTime.Now;
e.Values["customer_update_date"]
= null;
DropDownList ddl_CountyInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountyInsertDDL");
DropDownList ddl_CityInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CityInsertDDL");
DropDownList ddl_CountryInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountryInsertDDL");
e.Values["customer_county_code"]
= ddl_CountyInsert.SelectedValue;
e.Values["customer_city_code"]
= ddl_CityInsert.SelectedValue;
e.Values["customer_country_code"]
= ddl_CountryInsert.SelectedValue;
