How To Dynamically Assign The ImageUrl Property Of An Image Using Data Binding

Nov 11, 2010

I've got a SQL Server database with a table in it, which lists the file names of images. It's my intention to assign the ImageUrl of an Image control on the page, from the data in the table. I've placed a SQLDataSource control on the page, and then tried putting a FormView control there, and an Image control within that. But I don't see how I can assign the value to the ImageUrl property via data binding.

Web Forms :: How To Use AddHandler To Dynamically Assign Events To Dynamically Created Buttons

Feb 14, 2011

I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.

On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.

So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.

On my Page_Load, I'm running this after the buttons and labels are displayed:

For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next

I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.

Collection Of Property=>Value?

Jul 15, 2010

I would like to create a collection of key, value pairs in C# where the key is a property of an ASP.net control (e.g. ID) and the value is the value of that property. I would like to do this so I may later iterate through the collection and see if a given control has the properties in my collection (and the values of the properties in the control match the values defined in my collection). Any suggestions as to the best way to do this? Pseudo-code example:

Properties[] = new Properties[] {new Property(){name="ID",value="TestControl1"}, new Property(){name = "Text",value="Type text here"}}
private bool controlContainsProperties(Control control){
foreach(Property Property in Properties[])
{
if((control does not contain property) || (control property value != Property.Value))
return false;
}
return true;
}

DataSource Controls :: Assign A ParameterPrefix Property To A GridView?

Feb 23, 2010

I have a GridView that displays records based on a SQLDataSource, which gets it's data from a very simple stored procedure. I want to use stored procedures to update & delete records in the GridView, which I have done in the past.

Our organization requires that the names of the parameters within our stored procedure start with "@p" to differentiate between passed parameters and internal variables. This is causing me my issue. If I change the stored procedure code to reference the fields without the "p", everything works properly. This is because the SQLDataSource parameters use the default ParameterPrefix of "@" and correctly references the stored procedure parameters. Here is the relevant code:

[Code]....

I found a MS article describing how to override the default ParameterPrefix, but I am unable to implement it. I can add their example code, but how do I "assign" this property to my GridView?

Feb 17, 2010

I got 2 listboxes in a window form, one on left and one on right. The 1st listbox have some items while the 2nd listbox is empty. Also there are 2 buttons between the 2 listboxes which used to move item from/to the 1st and 2nd listbox.My problem here is that after I bind the data to the 1st listbox (from a dataTable, using DisplayMember and ValueMember) , and I try to move 1 of the item from this 1st listbox to the 2nd listbox and I want that the selected item is also removed from the 1st listbox by:

lbMembers2.Items. Add(lbMembers1. Text);
lbMembers1.Items. Remove(lbMembers 1.Text);

But the selected item is not removed from the 1st listbox.Also on deselect button when i move item from 2nd listbox to 1st listbox,it displays error message "Items collection cannot be modified when the DataSource property is set."

Custom Server Controls :: Creating .NET UserControl With Collection-type Property?

Feb 21, 2011

How can I create a UserControl with a collection-type property which has a collection editor?

I've a CompositeControl with an ArrayList-type property which has CollectionEditor-type designer. You can see this property on Properties window with a "..." button which launches a collection editor. This works fine and all but I want to apply the same to a UserControl and I've couldn't manage to pull it off so far. I've done the same thing what I've done with my CompositeControl but the property either doesn't even show on Properties window of the UserControl or shows as a single value property with no "..." editor button.

This is what I've done with CompositeControl:

How To Assign A Control Property Value From A Global Variable In Page Code

Entity Framework 4 - Check If Navigation Property Collection Is Empty, Without Include() Or Load()?

Sep 28, 2010

In an MVC view, I'm looking for a way to determine if a parent entity's collection of child entities is empty, so I can decide if I need to call a RenderPartial() or not.

For a one-to-one I've been using the following:

<% if (Model.Book.GenreReference.EntityKey != null) %>
{.....}

but I'm unsure how to do it in a one-to-many scenario, or if it can even be done without the use of Include() or Load().

Forms Data Controls :: Cannot Assign Values To Checked Property Of Checkbox At Runtime

Apr 22, 2010

I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.

When page loads,I get error - Specified cast is invalid!

The code is as follows...

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<Columns>
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<EditItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />
</ItemTemplate>
</asp:TemplateField>

Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.

Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.

I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.

I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.

Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.

how i can edit and update Checkbox.

where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.

Dynamically Add Items To A Collection In MVC2 Using EditorFor()?

Jul 12, 2010

I'm trying to do this: Editing a variable length list, ASP.NET MVC 2-style

In the post he mentions that it could be done with less code using Html.EditorFor(), but that it would be more difficult because of the indexes. Well, that's exactly what I want to do, and I don't know where to begin.

Update 1: Instead of generating a GUID for each item in the collection, I'd like to generate incremental indexes starting with 0. Right now the field names look like "gifts[GUID].value"; I would like them to be "gifts[0].value","gifts1.value" etc. but I don't understand how the collection keeps track and generates these indices.
