I remember I read a tutorial at asp.net. The tutorial is to add a row to display the category name before a different category starts in a GridView that displays products ordered by category. But I cannot find the tutorial anymore.
View 5 RepliesI have a datalist in my site which displays html tables filled with data from a sqldatasource. I need to be able to remove one column from the table and put it back again (including the tags in my table which pull the data from the datasource e.g. <%# DataBinder.Eval(Container.DataItem,"Forecast1") %>) I need to be able to do this because I have options to change the sqldatasource query, and I need to alter the table to keep it compatible with the query. What is the best way to do this?
View 4 RepliesI have a gridview to which I'm adding template fields programmatically. Each of the template fields have a textbox. I would like to make this text box have 2-way binding to a database column. see below code.

How can I make the text box such that when I edit the text, this change is reflected in the database as well?
I have datagrid and inside this grid have template field. I add Header text progr. like this

But when I do this I can not sort this column when add SortExpression="Hi"
I have a website developed in C# with Visual Studio 2010. I am using datalist to list the documents for monthly meetings. Each monthly meeting has 6 datalists representing each section of the monthly meeting. I am using row filters to filter the data for the respective month and section. I am using the Membership Provider model and am displaying the documents for the respective user. When a user clicks on the document link the document is marked and displayed as "read". This is all working as it should in my existing code.
However, I would like to be able to display this data programmatically. My oldest data is December 2009. I would like to dipslay this data programmatically based on todays's date and then looping back until December 2009. Today, I update the web form and the code behind on a monthly basis and I know that there is probably a better way to do this. I think this can be done but I am not certain if it can be done with row filters, because amongst other things I do not know how I can dynamically generate the datalist ids so that I can then bind the row filtered data.
Below is a sample of my code for one month of data.

I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?
I have the following line to display a piece of data and I want to know how I can format the output.
Text='<%# Eval("DOH") %>'
The data list displays the correct data, but I want to format it. The output I want is just a small date format instead of date and time. I have tried every combination of a format function I can think of, but can't seem to make it work. Am I stuck with the raw format provided by the database? I wouldn't think so, but maybe that is the case.
expected output should be 02/15/2011 instead of 02/15/2011 09:45:
According to the docs. [URL] There is an Separator Template for a DataList. However, when I use the built-in tool tip help, it does not show. If I manually type in a separator template it crashes my design time environment completely...
Not sure what I'm missing here. I tried an imagetemplate and a line but thats not really working because I need the image in the data field area not the headertext area.
I have a test page that I am trying to add a custom control (articleWUC.ascx) and set its properties to some results from SQL. I followed several guides including this [URL] with no luck.

I want to show a message when there's no data in my datalist. I found the following, but, I get an error on the bool. If you have another way to do this, great, but, I'd also like to try to do it this way as a learning experience.
<asp:DataList id="DataList3" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:HyperLink ID="ID" runat="server" target="_parent" NavigateUrl='<%# "Employment_detail.aspx?"%>'

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 need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
View 8 RepliesI have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:

Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

Context: In an ASP.NET application, I need the behavior of the ItemTemplate / EditItemTemplate that the DataList control provides. However, I only need one item in my control, which makes the DataList seems like overkill.
Question: Is there a control in ASP.NET made to store a single item that has the template content behavior of the DataList and DataGrid? Should I use a DataList for only one item?
In our current ASP.Net Webforms application we have several composite/template server controls that only exist for a common look and feel. For example, we have a panel control that has a title, a place for buttons related to the contents of the panel, and of course the contents. How is this best accomplished in MVC? RenderPartial doesn't get done what I need here. Should I still be using the same controls, but just on a view page? These controls don't really do anything on postback, they are only there for a common look and feel.
More Info:
We have a control in Webforms that implements ICompositeControl. We have a few properties on this control like Panel (type Panel), Buttons (again type Panel which would hold buttons) and a property Title of type string. Visually it looks like
