I've used <%# Container.ItemIndex + 1 %> to successfully add line/row numbers inside of a repeater control starting with 1, but I've run into a challenge where I need the line numbers to begin at row 50.

Say I have:

<th>Name</th>
<th>Secret Info</th>

</HeaderTemplate>
<ItemTemplate>
<tr>
<td><asp:Label ID="Label1" runat="server" Text='<%# Eval("Name") %>' /></td>
<td><asp:Label ID="Label1" runat="server" Text='<%# Eval("SecretInfo") %>' /></td>

<td><asp:Label ID="Label1" runat="server" Text='<%# Eval("Name") %>' /></td>

How would I only display the 'Secret Info' column to logged on users?

I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:

</ItemTemplate>

I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Below is the code to fill the grid, paging and fill repeater on rowdatabound event of grid.

View 6 RepliesI have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns()
{
// The first column to begin to insert the columns in the GridView
int columnIndex = 5;
BoundField aoColumn = new BoundField();
aoColumn.HeaderText = "New Column 1";
gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback
gvMyGrid.Columns.Add(aoColumn); // works fine
columnIndex++;
foreach (MyEntity my in _myEntityCollection)
{
BoundField myColumn = new BoundField();
myColumn.HeaderText = String.Format("{0:d}", my.StartDate);
gvMyGrid.Columns.Insert(columnIndex, myColumn);
columnIndex++;
}
}
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.
I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

View 1 RepliesI've created a new ASP.NET website. I've generated an Entity Data Model from my database and have dropped a entitydatasource and gridview onto my page and wired up the gridview to pull from the entitydatasource. Now I get columns like this: id extension prefix did_flag len ten_id restriction_class_id sfc_id name_display building_id floor room phone_id department_id
In each case where the item is named something_id this reflects a foreign key relationship in the database - and I did choose to have the EDM expose foreign key relationships. I'd like to make it so the gridview pulls in the values for these foreign keys rather than just showing the ID numbers - so, for example, department_id might have a value of "101" right now but it should pull from the department table "Marketing".
GridView1.Columns.Count is always zero even SqlDataSource1.DataBind();
But Grid is ok I can do
for (int i = 0; i < GridView1.HeaderRow.Cells.Count;i++)
I rename request headers here but
GridView1.Columns[i].Visible = false;
I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?
I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
