Forms Data Controls :: Programmatically Change ItemTemplate Eval Statements?

Dec 21, 2010

I have a GridView with an TemplateField:

<asp:GridView runat="server" ID="gvReport" ondatabinding="gvReport_DataBinding">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:Label runat="server" Text='<%#Eval("answers") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions") %>' />
</ItemTemplate>
</asp:TemplateField >
</Columns>
</asp:GridView>

What I'd like to do on gvReport_DataBinding is change the field the Evals point to, so I end up with something like:

<asp:Label runat="server" Text='<%#Eval("answers_foo") %>' /> out of <asp:Label runat="server" Text='<%#Eval("questions_foo") %>' />

I have gotten this far:

TemplateField tf = ((TemplateField)gvReport.Columns[0]);

But I'm not sure what I should be doing with tf. tf.SomeProperty.Replace("answers", "answers_foo")?

Or am I barking up the wrong airplane on this one?

Forms Data Controls :: Repeater ItemTemplate - If Eval(field)=0 Then HTML Else HTML

Feb 20, 2010

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.

Forms Data Controls :: Setting Text Programmatically In ItemTemplate Of Gridview Does Not Show

Mar 7, 2010

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.

Forms Data Controls :: TemplateField Change Itemtemplate Label CSS Depending On Column Value For Each Row In Gridview?

Jan 28, 2011

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.

C# - Getting The Object Inside Repeater ItemTemplate With / Without Eval

Nov 13, 2010

I am new to Repeater and DataBinding

In PageLoad, I have

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?

Forms Data Controls :: Select / Insert Statements In Buttonfield In Gridview

Jul 28, 2010

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]....

private void BindGridControl()
{//method created so that the binded gridview can allow paging controls
DataTable dt = new DataTable();
try
{
/*Gridview requires another column either a checkbox or a hyperlink column that
* can drill down another level and load a page where user can edit the data/cheque
* Will place an exception here that will prompt a window to notify users that
there were no rows returned
*/
GridView1.Visible = true;
sqlConn.Open();
sqlSearch = "select store_nbr as [Store number],date as Date,data_type as [Data type],acct_1 as [Account 1], ";
sqlSearch += "amt_1 as [Amount 1],acct_2 as [Account 2],amt_2 as [Amount 2], ";
sqlSearch += "acct_3 as [Account 3], amt_3 as [Amount 3], cheque_nbr as [Cheque Number], ";
sqlSearch += "cheque_amt as [Cheque Amount], gst_hst as [GST/HST], qst as [QST],comments as [Comment] ";
sqlSearch += "from SimpData where store_nbr = '" + StoreNum + "'";
sqlCmd = new SqlCommand(sqlSearch, sqlConn);
SqlDataAdapter adapter = new SqlDataAdapter(sqlCmd);
adapter.Fill(dt);
if (dt.Rows.Count > 0)
{
//if there are rows returned bind the datasource to the gridview
GridView1.DataSource = dt;
GridView1.DataBind();
}
else
{
//label control notifies user that there are no rows found
lblResults.Text = "Search returned no rows";
}
My ButtonFields<Columns>
<asp:ButtonField ButtonType="Button" CommandName="Select" HeaderText="Select item"
ShowHeader="True" Text="Select1">
