I am looking to use a gridview as an array that does not get loaded with data, instead I would like to use it as a grid which contains textboxes that the user can enter information in to, which I will read.Is this the right control to use? If so, how do I make the grid visible when I am not binding any data to it?

I'd like to make a page that displays information from my database, but in an atypical way. Each record from my data includes an image and some information about the image. I'd like to display an array of images, each with its associated data underneath the image. I'm imagining a table with four columns and in each cell there is an image and underneath the image is information about it (name, size, author).
You can get an idea of what i'm trying to achieve by looking at this webpage:

I'm dynamically loading a user control with a form view inside, when I'm trying to update the form view the user control disappears on the post back and update never happens;
View 3 RepliesI have a form in formview which uploads data to my mssql databse fine. I want to send an e-mail after the data is uploaded to supply notification that someone has filled out the form. I am trying to use OnItemInserted to achieve this. This is the error message I get:
Compiler Error Message: CS0122: 'Personal_Loans.ClientappFormView_ItemInserted(object,
System.Web.UI.WebControls.FormViewInsertedEventArgs)' is inaccessible due to its protection level
linked to the line of code for the formview:
<asp:FormView ID="Clientapp" runat="server" DataKeyNames="Key" DataSourceID="ClientData" DefaultMode="Insert" OnItemInserted="ClientappFormView_ItemInserted" >
My code on the page behind is this:
void ClientappFormView_ItemInserted(Object sender, FormViewInsertedEventArgs e)
{
TextBox email = (TextBox)Clientapp.Row.FindControl("email");
DropDownList title = (DropDownList)Clientapp.Row.FindControl("title");
This is then followed by the e-mail sending code. The servers CAS level is set to "full" I have tried using capitals and all lowercase for OnItemInserted I get the same result.
I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.
View 9 RepliesI have a dynamically loaded usercontrol
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucEditPanel.ascx.cs"
I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate. I present the data in a FormView ItemTemplate using text boxes. When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.
I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course . This project is different in that I want to get the data from a stored procedure on a MSSQL server.
In my latest attempt, I can see the data in the datasets. I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value"
I include the code below. If someone could point me to an example I would be greatful. There has to be an elegant way of accomplishing this.

I have a datalist in which i want to do away with -- change to data recieved into an array list.
Goal: This is a working code. Instead of setting the datasource (TABLE) for the DataList -- I want to set the data table to an array list

xUserAccess.UserAccess(txtEmployeeID.Text)
If xUserAccess.errorFlag Then
lblErrorMsg.Text = xUserAccess.ErrorMessage
Else
DDLUserAccess.DataSource = xUserAccess.UserData

DDLUserAccess.DataBind()

I need to have a Repeater with the letters of the Alphabet, when the letter is clicked on it returns all the "names" that start with the corresponding letter in a gridview.
I have got a basic repeater below working but when I tried to change it to a LinkButton I seem to have problems with the CommandArgument.

I have seen some close examples of this in C# but I need it in VB and the converter I use says incomplete snytax.
I have an array in my code behind page. say:
int[] Hour = new int[24];
I also have a dropdownlist on my aspx page. say:
<asp:dropdownlist id="ddlHour" runat="server">
I want to bind the value of array to the dropdownlist such that when I dropdown the list, I get to see the values from 0 to 24.
I have an array that I need to display using a feature like listview. Is that possible? I need to be able to display a "temporary" list of information that the user may add or delete entries. Once they approve the list I will loop through the list and store the information in a table.
View 4 RepliesI have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.
