I have a ListView bound to a database view (vw_Reunions). The Eval statements in the ItemTemplate render the data in vw_Reunions just fine but I have one in the LayoutTemplate that doesn't display. Can anyone tell me why?
Can anybody tell me how I can add ItemTemplate to a Template column in a GridView. What I am doing right now is that I am adding Columns to GridView from code. And now I need to add a Template column with a ItemTemplate.
I'm trying to programatically reference a FileUpload control which I have within an ItemTemplate. I get a 'Name FileUpload1 is not declared' error message. Code below:
The following seems reasonable, but it returns an error:
<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" > <ItemTemplate> <% If Eval("Item_Batch") = 0 Then %><tr><td></td><td colspan="2"></td><td></td></tr><% Else %>........
Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.
The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.
On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.
I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.
I have a gridview with a dropdownlist in one to the headers. So on the onselect event of the dropdownlist I want to change the assigned values of itemTemplate values inside one of the columns.
I need the yoy var %, bm % yoy bps, and opps generated to have a backcolor of gold. before it was a itemtemplate it was easy to change it in the codebehind but now that it is a itemtemplate it wont change anymore.
I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.
var photos = from p in MyDataContext.Photos select new { p, Url = p.GetImageUrl() }; repeater1.DataSource = photos; repeater1.DataBind();
In the Repeater control, I have
<ItemTemplate> <% Photo p = (Photo) Eval("p"); %> <!-- Apparently I can't do this --> ... <asp:TextBox runat="server" ID="txtTime" Text='<%= p.Time == null ? "" : ((DateTime)p.Time).ToString("dd/MM/yyyy HH:mm:ss") %>' /> ... </ItemTemplate>
But that is wrong.
What I need is to get the Photo object in ItemTemplate so I can do things with it (eg. to display the time as in the second line in ItemTemplate above). Is it even possible to do this in a Repeater?
I have done the itemtemplate and edittemplate,when I click on the button in itemtemplate, the edittemplate will show.But that row in itemtemplate will disappear.How can I keep that row in itemtemplate and ecotent in edittemplate both appear?
I have a gridview that has certain values in it that I would like to change based on a condition. For example, if a value in the column is 'x', I would like to make that Value Bold and have text that says 'Not applicable'
How can I do this? How can I programtically chnage values in a gridview?
I'm using the 'Configure Data Source' wizard to connect to my database and show the dataset in Gridview. I want to be able to update, insert and delete entries but am unsure how to build the query. I can write simple update statments to change database entries but how can I do this for entries that have been changed within the gridview?
A bit new to buttonfields in gridviews - Did a bit of research and most of the stuff I came up with had the gridviews with data bound like so :
[Code]....
