Forms Data Controls :: How To Access The Pageindex Gridview Property When Creating A Dynamic Template
Mar 15, 2011
I need to get access to the page index of the gridview so I can correctly get some data from a coresponding array to set the cell's contol properties correctly. Below is what I've got so far. The ExcelObject is a class that houses both the data read in from an sutomer submitted excel file and a matching 2 dimensional array of characteristics that I use in this case to set the CssClass property. My problem is that when I enable paging for the gridview I don't get the proper datasource row index when the data is read by the databinder.eval; what I'm getting is the current row of the gridview being generated.

How do I access GridView Page Index in RowDataBound event? I am assigning PageIndex to hyperlink on the gridview, for this I was planning to use "GridView1.PageIndex" in rowdatabound event. Problem is when I got second page in gridview (10 rows per page), the first row in the page shows page index as "0" and from second row it becomes 1. And if I goto third page, the first row in the page shows page index as "1" and from second row it becomes 2.

I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.
//Dynamically creating the Grid
protected void btnAnalyze_Click(object sender, EventArgs e)

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

I have a GridView which contains photographs.
Each row has a "View Large" link which passes the image id to another page whereupon the image is displayed in a DetailsView.
That page has a "back to album" hyperlink.
All this works nicely, however, no matter what page the user was on in the GridView, having clicked through to the DetailsView and then back to the GridView, the user ends up on page 1 of the GridView.
How can I ensure the user comes back to the same page in the GridView that they were on when they clicked through to the DetailsView? Do I need to pass the gv.PageIndex value and send it back; can I just somehow tell the GridView to "stay where it was"?
Here's the code for the GridView (it pulls the image info from a SQL db:

I am using a gridview on an OrderList page to present data from a database. Paging is enabled on the gridview.
Each row provides a link to an OrderDetails page which is used to display/edit data for the selected order.
I want to be able to return from OrderDetails page to the OrderList page and to set the gridview pageindex.
What is the best way to do this?
Can I have multiple paramaters with NavigateURL (i.e. the orderid and the pageindex)?

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.

Hello Good Day,
I want to change the ItemTemplate of Repeater based on different queries on my database.
Scenario -
Say for example,
- First query returns EmployeeID, EmployeeName - In this case repeater should display both fields.
- Second query returns EmployeeID, EmployeeDOB, EmployeeMemo - In this case repeater should display all three fields.
However this cant be done if I set hardcore EVAL in the markup. So i need it to be Dynamic.
Possible Solution in my opinion -
I found one way, that is creating a dynamic Template and then assigning its fields during Item_DataBinding.
Question -
Is there any other simple method, other than creating a dynamic Template all from its scratch. Means let me say, I hardcore fields like
EmployeeID, EmployeeName, EmployeeDOB, EmployeeMemo in the MarkUp, but in case of first query it (Repeater) should neglect
EmployeeDOB, EmployeeMemo and in case of second query it should negect EmployeeName.

I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.

I'm trying to make a form where the text boxes and titles for each box are created dynamically based on how many array values there are. I have tried a repeater but am a little unclear on how I can get the texbox to bind to one area of and the title to bind to another. This is what I have so far:
[Code]....
...and this is the code-behind with an associated array, arr1:
// Bind Array to Repeater
rep1.DataSource = arr1;
rep1.DataBind();
This works and adds values where container.dataitem is but how to I make it add one set of array values there and another set of array values where the *x* is?
