I got this at my page design. How can I set those properties at runtime?

I am able to do it for these properties,

But I do not know how to do it for BorderStyle, OnDataBound, Font-Name.
The most important item is the OnDataBound.
I have a nested gridview which has been working fine. Now I need to turn the inner gridview off based on some condition: a IF block is added to the existing RowDataBound event of the outer gridview. Now I'm getting "the Object reference not set to an instance of an object" error. What should be the proper way to go about this? The code:
[code]....
In addition, is there a way to "switch" columns of the inner gridview? For example, column 1 is "City", column 2 is "Price". If user selects to sort by "Price", I woud like column 1 be "Price" and column 2 be "City". Is this has to be done programmatically or if there's other way?
I have GridViews in mostly all web-pages. If data rows are too much then by scrolling down the grid, header misses.

I have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.

View 5 RepliesI am in need of some assistance in regards to how to best set the values of properties for a Web User Control which is being included into a cell of a GridView with dynamically created columns. I have tried a few different approaches, but can't seem to get a satisfactory result. Also, to be completely honest, I am not really sure if I am using best practices for what I am trying to accomplish.
First off a little background:I have a GridView for which we will never know the exact number of columns at run time. The columns are predicated by user selection. I am creating the command text for the DataSet on the fly and then looping through the columns of the resulting DataTable in order to use custom TemplateFields. This works ok for just printing out the row values but not so much for when I need to insert the Web User Control into a cell.The Web User Control is in essence a collection of image links which are used as a "Quick Nav" tool. I need to pass the values of 2 fields from each DataRow to the control via properties (for example, CustID and ProductID). I am using custom TemplateField classes inheriting from ITemplate for displaying my fields and extending the DataBinding event like so: [Code]....
This won't work for my User Control as DataBinding is called after the control is loaded into the page and I need the properties to be set before the Page_Load event of the control is fired.Is there a GridView event I should be looking into instead such as RowCreated or RowDataBound? Or should I modify how I loop through the DataTable by doing rows first, then the resulting columns as I've seen done elsewhere?
Is it possible to access textbox text properties from codebehind when gridview is edit mode? for example I can access label's text properties on gridview row databound event.
[Code]....
So I do not like use Text='<%#Eval("ColumnName")%' this method. I want to manage textbox text properties dynamcily codebehind when click the edit button on gridview. When I clik the edit button these code blocks runs
[Code]....
but rowdatabound event fires again and couldn't find label control. It looks for textbox control to bind data but I can not manage this step.
I'm face of a little problem when using GridView, an EntityDatasource and entity custom properties using a partial class. I'll describe it and I hope that someone has already find the solution because I try to figured out since two days.

Now i need to Bind it to gridview, the gridview columns should be
Date,IN,OUT,IN,OUT
In punched time the first one should be IN and second OUT. A employee would have punched several time a day. Based on that I should take maximum punches and bring that of columns as IN and OUT in gridvew dynamically. How to achieve this?
All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.

How to read this file and bind data to gridview control.
Right now i am using the following code but it stores whole data in a single column and a single row but i need it in four columns named NC, WC, PRC,ETAC and it's values in respected columns.
Code:
protected void Button1_Click(object sender, EventArgs e)
{
String ext = System.IO.Path.GetExtension(FileUpload1.FileName).ToUpper();
if (ext == ".TXT")
{
String content = System.Text.Encoding.ASCII.GetString(FileUpload1.FileBytes);
String[] ar = content.Split(';');
GridView1.DataSource = ar;
GridView1.DataBind();
}

how to get data in four columns in Gridview as a tabular format. I am using technologies Visual Studio 2005, ASP.NET 2.0,C#.NET 2.0 and Windows Xp Operating system.
I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.
I have a Transport Detaisl in DB , i want to dispay data on gridview with marquee scrolling up. Cabs are scheduled for drop every hour.

I would like to display time difference between previous row in GridView.
I prefer creating new Column in SQL, but I can't come up with getting value from "last row" in SQL statement.
The reason is that I would like to have Total hours.

2 | 1/1/2010 2:00:00 am | 1:00

View 5 RepliesI have a simple GridView with AutoGenerateColumns,Edit and DeleteButton = true
It's data source is a DataTable dynamically generated.
Since i don't want to use object data source, i just catched Delete event and deleted rows from datatable and made a new databind. It works.
I tried to use also AutoGenerateEdit button, but when i click on Edit command field, nothing happes. So i decided to handle by myself edit events, and changed datagrid in this way:
<asp:GridView runat="server" ID="dettaglioprodotti" BackColor="White" BorderColor="#DEDFDE"
I am developing an applicaion for time sheet which uses gridview.
The columns are dynamically generated based upon the start date and end date.Its a biweekly pay period.
Apart from these 15 Day 1 to Day 15 columns there are 5 other columns for different codes which are added to gridview using data table. I have drop down list control for the 5 codes and text boxes for the remaining day 1 to day 15 columns.
Now when the user selects the values from the drop down list and enters the number of hours into the text box using a footer row with a inert link button it should add the values entered to the footer row to the data table data row and then rebind the data table to the data base. I am some how unable to get the values entered by user into the footer following is the code for insert_click event
Protected Sub lnkInsert_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim tb As TextBox = GridView1.FooterRow.FindControl("txtctrl6")
End Sub
