How To Select A Gridviewrow Based On Textbox Value
May 20, 2010
I have a gridview that is selectable. Below it I have a dropdownlist and a textbox. The dropdownlist has the options for each column in the row(I am using an ajax autocomplete extender that checks for related values in the textbox based of which dropdownlist value is selected.) I want to take that a step further and see if I can select a row based on what is in the textbox on the textchanged event. Right now im playing around with using a datatable and then filling a string[] of whatever column the dropdownlist is selected on.
protected void txtFilter_TextChanged(object sender, EventArgs e)
{
DataTable dt;
SqlCommand cmd = new SqlCommand("SELECT * FROM General", csbg2);
SqlDataAdapter da = new SqlDataAdapter(cmd);
dt = fillDatatable(cmd, da);
string[] items = new string[dt.Rows.Count];
switch (ddlEducation.SelectedValue)
[code]...

I have a checkbox and a textbox in a GridView (for every row), and I'd like to be able to write some javascript that would enable and disable the textbox depending on the state of the checkbox (checked or unchecked). I guess I'd have to give JS the row index somehow.

I'm using 3 text boxes for allowing user selecting different ranges. I want to perform below validations on three text boxes.
1.User should enter a value (i.e. a valid number,doesn't allow to enter zero,decimal numbers and negative numbers) in 1st text box.
2. 2nd text box value should be greater than 1st text box.
3. 3rd text box value should be greater than 2nd text box.
I want to perform validations on client side only using JavaScript. If anything goes wrong I want to populate a message box.

I got an unusual problem. The solution is most likely very simple or completely impossible. I want to dynamically select a property based on a string value. I am using LINQ which automatically creates a class for each table. The actual columns in the table become properties of the class. I need a different column based on the current culture settings as the different columns contain translations. For example, if I want to set the text of a hyperlink to English I choose the EN column as follow:

I have a textbox which can be left blank or contain a date. If the textbox has a date I want the 2nd textbox's value to be set to the value of a session variable. I need this to happen before the update sql is performed on postback.
This is the code I have. But the textbox is coming back as nothing. Whether it has a value in it or not.

I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table. I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum. Here is the way I implement that. I am looking to prevent using "For each".
iRefund = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1.UnitCost).Sum
Dim objOrderDetails = (From od1 In dc.OrderDetails _
Where od1.OrderID =1 _
Select od1)
For Each OrderDetail As ORM.Entities.OrderDetail In objOrderDetails
If Not OrderDetail.Requests Is Nothing Then
IF OrderDetail.Requests.Last.RequestType="Refund" Then
iRefund -= OrderDetail.UnitCost
End If
End If
Next

If I have records in a table in this order:
Id - Date - Type
1 - 2011-03-01 - 1
2 - 2011-03-02 - 0
3 - 2011-03-03 - 0
4 - 2011-03-04 - (-1)
5 - 2011-03-04 - 0
Can I somehow select the records between a record having type 1 and type -1 without using a cursor,for example the records with ids 1-4 in this example?

Here's what I want to accomplish: I have two .aspx pages, the first page with a ddl to select a vendor (SelectVendor.aspx), and one to add a vendor (NewVendor.aspx), if it's not in the first one. If a user adds a new vendor on the NewVendor.aspx page I want the page to automatically redirect back to SelectVendor.aspx and have the ddl automatically select the new vendor that was just added. Here's where I'm at so far: If a vendor is not listed in the ddl on SelectVendor.aspx, a user can click a button to navigate to a page to add a new vendor (NewVendor.aspx). On NewVendor.aspx the user types the name of the new vendor in a textbox and clicks an insert button to add the new vendor, then the page is automatically redirected back to SelectVendor.aspx with the new vendor name added to the QueryString. For example, let's say a user adds a vendor name "Best Vendor": The page is redirected back to SelectVendor.aspx as "SelectVendor.aspx ?vendor=Best Vendor"Now all I need from here is to have the ddl programmatically select the new vendor by the text value in the QueryString.
Here is the code that I'm having trouble with from my Page_Load routine for SelectVendor.aspx:

Which intellisense says "Property Access must Assign to it's property or use it's values". Do I have the code all wrong? Also, as a side question, I don't understand why I have to use the TryCast find control option to find every control to use them. Even in the Page_Load if I type in DropDownList1 it says it's not declared.

I am working on some ASP.NET web forms which involves some dynamic generation, and I need to add some onClick helpers on the client side. I have a basic outline of something working, except for one huge problem.
There are multiple HTML tables, each generated by a different ASP.NET web control. Each table can contain overlapping field names, which is causing a problem with my JQuery click event handlers. The click event handler is linking to unintended form fields in addition to the intended form field.
I have provided a simplified sample version of the code below. This code is trying to set the value of textbox box1 when a particular radiobutton is selected in the table with id=thing1. Obviously, the jquery code will be triggered for the form fields in both tables.
The tables are dynamically added to the webpage based upon different conditions. It is possible that no tables will be loaded, only 1 table, or both tables might load. In the future, other tables could be added. Each table comes from a different .net web control.
Other than renaming the form fields to make sure they are unique across all user controls, is there a way to have JQuery act only on the intended form fields? In other words, could the table ID be incorporated into the JQuery code in a manner that does not become a nightmare to maintain later?

i have a web site that uses forms authentication. the problem is that i have the site installed multiple times on the same production servers because i need to have a few different login pages (based on the domain in this case). after the domain specific login page, the rest of the site is the same. obviously, this requires a lot of maintenance as each new version has to be installed multiple times on the server (with varying the login page in the web.config file).
so i thought is there a way to install the site on 1 folder on the disk, have a web site on the IIS take in all the needed domains and make some http module (or some other solution) in which i could give it a list of domains and the forms authentication for that domain. this way make the login page used by each site change according to the domain while still having only one site to maintain on the server.

I have a page with a Listbox and GridView.
The Listbox has a list of students. The Gridview has a list of classes offered during a period, such as:
Math Science English etc. When I click a student in the Listbox, I call a sproc via Linq, and get the ClassID and ClassTitle that student is registered for.
What I need to do is Highlight the record in the GridView that matches the ClassID or ClassTitle returned by the sproc.
Previously, I used a ListBox for the Class Offerings. This is easy with a Listbox using the FindByText method:

I have two tables. One table containing 1 master record and the other table containing multiple records per 1 master record. I want to only display in a gridview (or whatever is best) the master record AND its assocated detail records IF certain fields in the detail records are there. I have been trying to figure out how to do this but I am still a bit of a newbie and I don't how I can do this.
