assuming there is no ComboBox control in ASP.NET (or is there?????) : I want to create such a control preferrably using the DropDownList control.
View 3 RepliesI've got a dropdownlist control that the user can select an an employee name and that should then fill in the detailsview control with specific information about that employee.
My dropdownlist control works fine and I do have AutoPostBack set to true. For some reason my detailsview doesn't work. There's no error message. The detailsview control just doesn't show up.

Finding DropDownList Control Within DataList Control?

<asp:LinkButton ID="AddBtn" runat="server">Add Committee</asp:LinkButton>

</asp:DataList>
I've put a DropDownList control within a LoginView control. I've got 2 SqlDataSource controls outside of the LoginView control, with the intent of databinding the items that comprise the ListItems of the DropDownList control, and another one for the data is stored in another table which has what was previously saved for the selection. However, when I've assign the SqlDataSource control to the DropDownList control's DataSourceID for the lookup table, I'm used to seeing the fields from the SqlDataSource control appearing in the DataTextField and DataValueField properties. However, they're not appearing there at all. Moreover, even when I try to type them in, its as if VS 2010 refuses to allow them.

How to apply the same tutorials for checkbox list control to filter the gridview instead of dropdown list.
I'm trying to add a validation support to DropDownList by creating a custom control inheriting from DropDownList:
public class MyDropDown: DropDownList, INamingContainer
{
private const string ValidatorID = "Validator";
private RequiredFieldValidator _validator;
[Code]....
My class implements INamingContainer because I wanted to avoid naming conflicts. Unfortunately when I try using this control I get the following exception:
Unable to find control id 'MDD' referenced by the 'ControlToValidate' property of 'MDD_Validator'
This is happening beause for INamingContainer FindControl(NamingContainerId) returns null.
When I remove INamingContainer implementation and set validator ID in the following way:
_validator.ID = String.Format("{0}_{1}", ID, ValidatorID);
Everything is working fine, and id given to Validator is the same as it would be inside Naming container.
But is there a way to accomplish this WITH INamingContainer ?
I have to show progress bar in datalist and having following scenario:
I am collecting response for the questions For each answer, total no of responses and their respective Percentage(%) is calculated
Now I have to show this % progress in progress bar
means if a answer have 100% response then progress bar show 100% (100% filled) if it have 50% response then only half of progress bar is filled (50% filled)and so on. response is calculated upto one decimal places(like it can be 33.3% or whatever)and respective % have to be shown in progress bar
So I have to create progress bar dynamically for each response %

View 1 RepliesI am in need of getting the correct sysntax for being able to use paging with a datalist whose data is being generated by a SQL Datasource and a stored procedure inside the aspx(asp.net VB...Not C#) page. A Gridview or any other rigid control that does not allow full control and layout will not work so I have to use the datalist. I have the datalist working perfectly but I need to add paging. I did some searching and found a good solution. It was a C# solution, in particular the code behind syntax so I used a code converter to convert it to VB. However, as I am not an experienced coder I need help converting the portion for handling the datalist. I am fairly confident I have the buttons on the aspx page worked out. I will ask that if you se something I need to do besides the section(5) I have listed please offer suggestions. So that you can help me better I have boken the code out into sections where I'm listing the code I copied, my code and the section I need help with. I think at a minimum I will have to change the references of Repeater to Datalist.
The section I need help with is section 5 where the original autor is referencing items generated in the Repeater where he used XML. As I said I'm using a SQL Datasource with a Datalist so I truly don't understand what I need to change to get the code behind to work with my Datalist. As always I appreciate all of you guys and ladies help. And also as always I will ask to please provide the actual code to type in because telling me how to do it just won't help very much. Sorry about that.

I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:
Dim DstBasket As New DataSet, TblBasket As New DataTable
With TblBasket
.Columns.Add("BskPrdCd", System.Type.GetType("System.String"))
.Columns.Add("BskPrdDesc", System.Type.GetType("System.String"))
.Columns.Add("BskQty", System.Type.GetType("System.Int16"))
.LoadDataRow(Split("12345,Test product 1,1", ","), True)
.LoadDataRow(Split("122,Test product 2,2", ","), True)
.LoadDataRow(Split("123A,Test product 3,5", ","), True)
.LoadDataRow(Split("44,Test product 4,1", ","), True)
End With
DstBasket.Tables.Add(TblBasket)
With LfnGridView("GdvBasket")
.DataSource = DstBasket
.DataBind()
End With
The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
On my webpage, jobs.aspx, I have a gridview which is populated from my database. I would like it so that when a row in the gridview is clicked, the ID of the row from my database can then be passed through as a query string to a second webpage, details.aspx, where more information about what was clicked on will be displayed.
I'm confident about being able to pass the query string, I just need help with getting the corresponding row's data ID from my database and making the gridview click-able, which will be the interaction which specifies which ID to be retrieved.
I have been using the GridView control, to display data, but now my two datasources (Informix, and VisualM/Mumps) makes it very difficult to create a store procedure to with paging. Is there a better data grid, that will allow my users to scroll/search the current data set?

I tried the following code changes on asp page: I changed "SelectedValue" to "Text" and still get the same error message I changed "SelectedValue" to "SelectedItem" and don't get the error message, but dropdown is not populated I set AppendDataBoundItems = true Set first list item value = "" Verified that every field in the table column matched the items in the dropdown list. There were NO null fields in the database.
I just want to understand this error message, as I have exhausted all that I am doing. I also made an attempt to bind the dropdown list, but sine this can only be done within the loop of finding the repeater control, I would either get an error message, or it just would not work.
here is my latest bit of insanity. I'm using a formview control. In the insert template, I'm grabbing applicable values from my AD to populate a dropdown list. I select the user I want to insert, enter the other pieces of info required for my request and click Insert. The query responds back stating that the userid is NULL. So the big question in my mind is how can I bind userid to the dropdownlist if I'm populating that from the code behind? Here's my code behind code for that list:
