Forms Data Controls :: Programatically Access The Link Of A DataList?
Jun 23, 2010
I am writing a system that is input intensive, and the used need to be able to use without touching the mouse. I am trapping the enter key and defaulting to click an "Enter" button that I have on the screen. In the EnterButton_Click event, I am using a "menu option" to determine which DataList item they want.
All of that is working great, except reading back the URL from the DataList Item, which I need for my repsonse.redirect to call the next screen.
[Code]....
I am inches away from pulling this off.Entire code is below. The actual datatable/datasource will come from a file later, I just mocked up some links for this example.

Working on a web part that will contain a datalist. How do you set up various properties such as ItemStyle, AlternatingItemStyles, and all the data binding?
I've search for some keywords but could not find anything relevant.

I have a datalist and the following link button within the datalist:
[Code]....
I would like to post to a new page and then capture the value from the link button (commandArgument). It appears from other threads I've seen that you have to rebind the datalist in order for the ItemCommand event to fire...is this true? I'd hate to make another DB call to bind my datalist just to make an event fire.

I have a datalist inside of an updatePanel. Within the datalist, for each item I have a linkbutton that when clicked I would like to fire the OnDeleteCommand of the datalist so that I can delete the record.
Problem is that I can never get the event to fire, it simply does a postback and then does not fire the event specified inthe "OnDeleteCommand" argument of the datalist control.
I've read many postings with similar entries, but nothing has worked.

I have the below label. I need it to be a link that will cause the following:
Existing label INSIDE a DataList Item Template;
<asp:Label ID="Label10" runat="server" Text='<%# Eval("CG_ID") %>' Font-Size="X-Small"></asp:Label>
I need to change this label to a link that will cause C# code behind to:
tbxCG_ID.Text = Eval("CG_ID")
and then call this:
protected void ListBox1_SelectedValueChanged(object sender, EventArgs e)
I keep creating a DataList1_SelectedIndex_Changed event created when I double click the label or a link button. What is the code needed? I can see the Eval("CG_ID") value with the label but I don't know how to get it into tbxCG_ID.Text and fire the ListBox1 event.

I want to access my checkbox in code behind. I have my checkbox in my aspx file like this:
[Code]....
And i'm trying to set the checkbox visible=false like this but it's not working. Error message: Object reference not set to an instance of an object.
[Code]....
This is just one thing i want to do with my controls in my datalist, so i don't want to in my aspx file like this:
<asp:CheckBox ID="CheckBox1" runat="server" Visible='<%# if(Eval("isFolder")="1","false","true") %>' />
Because i have quite a lot of things i would like to do in the code behind when i'm getting my files..
Is it possible somehow to achieve this without having to put servercode in my aspx file?

I can't seem to access a label that is outside the DataList. I wish to add the data in the label into a database, aswell as data that is inside the datalist (this is already working though). My SQL-query with only the specific label looks like this at the moment:
[Code]....
The data is added to the database when pressing a button inside the datalist (using onItemCommand). If I write UserIDLabel.Text the regular way it doesn't work either. The label is in the MasterPage, while the datalist is in a .aspx-page. If it is possible to somehow access the data that is in this label and add it to the database I would be ever grateful. Or is it somehow possible to add data that is in a Session and add it to the database?

i have the code to test:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =8", Con)
Now, I need something like this:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" + LblInfoEditar.text, Con)
The problem:
The LblInfoEditar is outside the datalist so it works fine. (note: in this label I put a value like the 8)
But I have this label to test because I need to access a label inside datalist:
<asp:Label Visible="false" runat="server" ID="LblNumEntrevista" Text='<%# Container.DataItem("EntrevistadoCodigo") %>'></asp:Label>
The problem is: in this line I've to put something to access this LblNumEntrevista HOW?
I try:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" +
ListaPendentes.LblInfoEditar.text, Con)
But of course I don't work because I can't do this...

I am using two data list one at the bottom & another at the Top to display paging. On Page load, I need to access link button placed inside Data List. Actually I had got two Datalists. I can access one Datalist Link button like this:
LinkButton lnkPg=(LinkButton)dlPg.Items[0].FindControl("lnkbtnpaging");
lnkPg.Visible= false;
This is giving no error. But if I write same code for another datalist say dlPg1, it is giving error: Index was out of range. must be non-negative.

I need to create a grid where the users can see all the memberships, and have a line of checkboxes for each existing role, and be able to check/uncheck roles to allow access authority.
I managed to build a datatable that adds columns and displays them properly, but I have not been able to programatically add columns to the grid based on whatever roles are stored in the system.
I can display the users and their roles by just specifying AutoGenerateColumns="true" when I do that, the checkboxes are grayed out, and the users do not want to have to click a button to open them up.
Here is what I can't figure out.
How do I programatically add columns to the GridView? I have some code in Pageload, but it doesn't work, so it is commented out?How do I turn on all the rows for the entire GridView to edit mode? How do I access the column name for the role they just checked so that I know what to add with the ystem.Web.Security.Roles.AddUserToRole(UserName, Role)?
