To Dynamically code delete button in Datagrid not to display if

[ASPNETnewbie]

I was wondering how I would handle a situation where I have an imagebutton in my Datagrid code for my Delete button not to display if the status of information being displayed is true. How do I handle this If I already have my Delete button stored in the Datagrid template?

Use the ItemDataBound event. In there you can check if a condition exists and set the visible property of the imiage button accordingly.

hey,

I used the information you provided me and I know you are right about how I need to work this but I don't seem to be getting it right.

what I have is this

protected void FormatDelButton(Object sender, RepeaterItemEventArgs e)
{
     if( (e.Item.ItemType == ListItemType.Item) 
     {
     string x=(String)e.Item.DataItem;
     if( Convert.ToString(DataBinder.Eval(x, "Moved")) == "USA" )
         ((Label)e.Item.FindControl("btnDelete")).visible = false;
         ((Label)e.Item.FindControl("btnDelete")).enabled = false;
     }          
}

basically what I want it to do is check the extra property of what is sent to the column and if the extra property is set to MOVED, I need it not to display the imagebutton in that particular column. Can you help with more information on how exactly I can handle this?

I don't know C# so my syntax may be off.. but something like this...

if (e.Item.ItemType == ListItemType.EditItem | e.Item.ItemType == ListItemType.AlternatingItem) { 
   DataRowView dr; 
   private object dr = ((DataRowView)(e.Item.DataItem));

   if dr.Item("Your Column" == "Moved") { 
      'Hide your Button code here..
   }
}

thanks.

I finally figured out the logic for the code but I seem to be having one problem. I would like to shut off the particular control which is itself contained in an Itemtemplate

<asp:TemplateField HeaderText="Rollover">
        <ItemTemplate>
       <asp:ImageButton ID="DeleteThis" runat="server" 
        ImageUrl="~/Images/Delete.gif"
     CommandName="DeleteMove" CommandArgument='<%# Eval("MoveID") %>' CausesValidation="false" />
</ItemTemplate>
[\code]

This is my code so far, however the lines 
[code]
((ImageButton)e.Item.FindControl("DeleteThis")).Visible = false;
((ImageButton)e.Item.FindControl("DeleteThis")).Enabled = false;

for some reason do not work at all.... Do I have it wrong?

Below is what I have

//OnItemDatabound event 
protected void FormatDeleteButton(Object sender, CommandEventArgs e)
{
string args;
int moveID = -1;

if(null != e.CommandArgument)
        {
            args = e.CommandArgument.ToString();
            if (DataValidation.IsInteger(args))
            {
                moveID = int.Parse(args);
            }
        }
        
        Movethis move;
        bool isBound;
        move = move.GetMove(moveID);
        
        isBound = (move.Status == moveType.Done || move.Status == moveType.Worked);
    
     if (e.CommandName == "DeleteQuote")&&
     {//disable the button itself if isBound evaluates to true
        ((ImageButton)e.Item.FindControl("DeleteThis")).Visible = false;
        ((ImageButton)e.Item.FindControl("DeleteThis")).Enabled = false;
     }
     
 }

Do you get an error, does nothing happen, is the event being raised?

 

[ASPNETnewbie]

Nothing happens... I mean intellisense does not even pick up on e.item in the code behind
