AJAX :: Dynamically Fill Textboxes And Choose Option In Dropdownlist For Modalpopupextender?

Sep 7, 2010

I have a modalpopup extender that is brought up if the user presses a button. This is fine and the user can enter the data. There are a number of textboxes and dropdownlists. However, I have a gridview which I want to bring up modalpopupextender so the user can edit an entery. How can I set the data to the controls? A dynamicpopulate extender will repopulate the modalpopupextender with all the data. It doesn't make sense for me. Is there anyway I can populate the data with c#? Also can I assign two buttons to call the modalpopupextender?

Forms Data Controls :: Show Data Relationship In Gridview With Dropdownlist Or Similar?

May 24, 2010

I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user.I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ):

[Code]....

But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID.The closest I've come to finding something similar to this is this for Linq2SQL: http://weblogs.asp.net/scottgu/archive/2007/07/16/linq-to-sql-part-5-binding-ui-using-the-asp-linqdatasource-control.aspx , and this using more traditional data access: ttp://www.highoncoding.com/Articles/169_DropDownList_Inside_GridView__Method_1_.aspx . Either way, regardless of data access technology, I can't relate these solutions to my example and get it to work

Forms Data Controls :: Unable To Bind Data To DropDownList In DetailsView

Sep 15, 2010

I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.

The scenario:

DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.

Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.

when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.

The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.

My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".

I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.

code:

The SqlDataSource used to select the parameters from the table and populate the DetailsView

Forms Data Controls :: Filtering GridView Data Via DropDownList Control?

Apr 10, 2010

I've got a GridView populated via a SqlDataSource whose Select command is controlled by a DropDownList. This is all working nicely:

How do I support the "All" user choice:

In other words, when the user selects "All" there are no aircraft names that match that so nothing is returned. Instead, I'd like the select statement to skip the WHERE clause in this case and just show everything. Do I need to create a second page for this case or is there a way to programmatically alter the SELECT command or some other way to accomplish this?

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?

I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ).

Forms Data Controls :: Unable To Sort Data-Bound DropDownList When AppendDataBoundItems Is True?

Apr 26, 2010

I'm having a problem sorting a dropdown that I've bound to a SQL Server data source. I've narrowed the problem down to the fact that I have a static item at the top of the dropdown with the data-bound items appended afterwards. If I remove the static item (<asp:ListItem Value="-1" Text="All" />) the ORDER BY part of the select clause works fine. How can I get around this issue? What I would like is to have the "All" static item at the top of the list with the data-bound items sorted alphabetically afterwards. I'm using Visual Studio 2010 and ASP.NET 4 if it makes any difference.

[Code]....
