I have a GridView :
[code]....
I want to query the value of a particular field in a DB and if it's true, display the LinkButton. if false, I want the linkButton not to be displayed.
is there a way to access the GridView programmatically and make visible certain of its columns or manipulate its items ?
I've got the following Setup in my Theme:
App_ThemesDefaultStyleSheet.css
App_ThemesDefaultPrintStyleSheet.css
The PrintStyleSheet.css file has a set of printing css rules set in them wrapped in an @Media Print { } block.
I need a way to programmatically remove the PrintStyleSheet.css from the list of css files for ASP.NET to inject based on some flags. (Some instances we want to print the site verbatim without custom formatting).
I know i could build a seperate theme without the PrintStyleSheet.css in it and switch the theme programmatically, however this would introduce duplication of my master stylesheet which is not acceptable.
Given a GridView control defined like this:
[code]....
The "FilePath" and "AttachmentID" fields are being set correctly in the grid, however, the CheckBox control is never set correctly; it is always unchecked.
My question:
How do I get this CheckBox field set from C# as I'm creating the new row?
P.S. I am not sure if I am creating the row correctly in the first place.

I have a gridview. In my RowDataBound handler I'm doing some things to columns, and accessing them like this for example,
e.Row.Cells(7).BackColor = System.Drawing.Color.Salmon So, of course when I rearrange the order of my columns everything breaks.
Isn't there some way to give an ID to a column, and say e.Row.Cells("TotalColumn_ID") ?
Will this work? Do columns have IDs?
I want to access the header text of bound fields programatically. suppose i have GridView1 with following bound fields:
<asp:BoundField Visible="false" DataField="ID" HeaderText="ID" /> <asp:BoundField DataField="Title" HeaderText="Title" /> <asp:BoundField Visible="false" DataField="Description" HeaderText="Description" />
how can I access their header text programmatically ( display it(either using response.write or any label)
I am new to the whole MVP thing and slowly getting my head around it all. The a problem I am having is how to stay consistent with the MVP methodology when populating GridViews (and ddls, but we will tackle that later).
Is it okay to have it connected straight to an ObjectDataSourceID? To me this seems wrong because it bypasses all the separation of concerns MVP was made to do.
So, with that said, how do I do it? How do I handle sorting (do I send over handler events to the presentation layer, if so how does that look in code)? Right now I have a GridView that has no sorting. Code below.

I hava a textbox and button in my project. I want the button on click to add a new column inside the database "Trial.mdb" , table name "table1". The column name will be text typed in the textbox and it will be text type. How could I do that? with a sql code in asp:accessdatasource or in my code behind ?
View 13 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.
in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]
View 1 RepliesGridView1.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?
Dim ds As New AccessDataSource
ds.DataFile = "c:InputTest.mdb"
ds.DataSourceMode = SqlDataSourceMode.DataSet [code]....
I apologize for the odd title. I've been trying to figure out how to do this and can't quite put it into words. Basically, I need to try to display a GridView with a whole bunch of columns (37 in one case) in two "rows" of columns. More or less.
So instead of this:
Column1 Column2 Column3 Column4 Column5 Column6
Data Data Data Data Data Data
Data Data Data Data Data Data
Data Data Data Data Data Data
I'd like something like this:
Column1 Column2 Column3
Data Data Data
Data Data Data
Data Data Data
Column4 Column5 Column6
Data Data Data
Data Data Data
Data Data Data
As in the example there can be multiple rows returned which all need to be displayed. I'm trying to stop a very large horizontal scroll bar being required. I've been searching as much as I can but haven't found anything that fits what I'm looking for.
In IIS 7 you can create database connection strings. I suppose this must be encrypted and best protected by IIS. This is nice, but how do I access it programmatically?

i know that i can set a Label's text by using this syntax:
lblMessage.Text = (string)GetGlobalResourceObject("resxFile", "message");
but what's the difference(benefit/drawbacks) to using this syntax:
lblMessage.Text = Resources.resxFile.message;
also, i just found out that this second method doesn't work for local resource files. is there a different syntax used for local resource files?
I've created an asp.net sitemap with nodes that I will have to make visible on the condition of the sql table the webpage of the node accesses.
Where is the code of my sitemap.
[Code]....
Here is the code I have tried.
[Code]....
Each time I run this code the item.target, item.value, item.text equals the sitemapnode title. Yet, it should be different than this. I was hoping to store the table title of the sitemapnode in the value property. The reason for this is to enable my boss to modify the sitemap without having to explore the C# code. I'm lucky that if I could get him to open the sitemapfile. He does not want to worry about the code breaking down when he makes an addition to the sitemap node.
I have found that I can change the value programmatically in C# but this would contrast with what my boss would want.
