How can I programatically call a gridview row when it is loaded based on the primary key. For example, say I have a record in the gridview where the column name is ID (Identity Field) and has the number 37 in it. When the gridview loads up, I need to get the rowindex where the primary key = 37 and have that row automatically selected.

I have a grid view with select button in cell[0], a column "comp_name" in cell[2], a textbox and a search button beside it.
I want when I enter a company name in a textbox and click on search button a row contains this company name is being selected.
I'm trying to add a second command field to an asp.net gridview. Essentially, I want the user to have the options to delete and update records on one page. I've gone through gui's to do this that I have found on the web but none of them work. I think that this is because of the fact that I am working with Visual Studio 2008, so the gui's don't match. Plus, my datasource isn't allowing me to add delete parameters, and update parameters. So, my present goal is to have multiple command fields in my gridview. This would also enable me to add a "duplicate record" functionality, as is needed with this program. I would also like add functionality. If possible. I've been doing all this on multiple screens but I believe I should be able to do this on one screen. Here is my gridview and datasource.

The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
give me an example of how to do this?

I have problems building a GridView programmatically. My code is:
[Code]....
This displays the GridView with the following problems:
1. The Html constructed in the Subject column displays on the page as raw Html. The source code shows the Html characters in their ASCII form. The function HTMLEncodeSpecialCharacters is obviously incorrect.
2. The PagerSettings display the page numbers only (1 2 3 4) and not the First and Last text (want to display << 1 2 3 4 >>) despite setting PagerSettings.Mode = PagerButtons.NumericFirstLast.
3. Clicking the page numbers is always one page behind. For example, when the page is opened, page 1 displays. If I click 2, page 1 still displays. Then click 3, page 2 now displays. Click page 4, 3 displays. Click 2, 4 displays etc etc.
4. The column headings are aligned in the centre despite setting HeaderStyle.HorizontalAlign = HorizontalAlign.Left.
I have a GridView which pulls info from a SQL DB. It works fine. I use a CMS to upload the data which includes thenumber referred to below.
The last (rightmost) column in the GridView is a number.
I'd like to know how to know how to:
1) Make a further column visible (to the right of the number) which contains a Button BUT only when the user is logged in.
2) Make that Button call a function (the workings of the function are irrelevant here) and pass to that function the number in the previous column.
I know I could use a LoginView with two GridViews, one for logged in (showing the Button) and one for anonymous (without the Button), but then I'd have to put the Button in the database... I think.
A better idea would be to add the Button column programmatically.
how this can be done and how the Button in each row, when clicked, can pass whatever number is to its left as a parameter?

I have already google the question, but couldn't found any relevant post.1) I want to make gridview's one column () editable according to some boolean value (flag).

View 1 RepliesI have to add row in gridview dynamically when a button is clicked on my page
Each Row which have to be added contains a dropdownlist(ddlQues) in which questions are binded
On selecting question from ddlQuestion I have to bind another dropdownlist(ddlAnswers)with respective
answers in that row of gridview
So autopostback property of ddlQuestion is set to be true
Everytime when button is clicked a new row is inserted in gridview and same process repeats............
I had tried following javascript:
<script type="text/javascript">
function AddNewRecord()
{
var grd = document.getElementById('<%= gvResponse.ClientID %>');
alert(grd);
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
and calling this function on button
<asp:Button ID="btnResponse" runat="server" Text=" New Response" CssClass="button3" OnClientClick="return AddNewRecord();" />
Also I tried to solve it by C#
By both ways(either by javascript or by C#)New Row is added in gridview
But when I select question from ddlquestion then page is loaded and and the inserted row in gridview disappears
I am using asp.net 2.0 with C#

I've programatically created a DataView item by adding columns and rows to a table in the class file. Then I add that to my webform using a GridView. I'd like to hide some of the columns so that the end user doesn't see them but still be able to access their values.
How do I do this programatically? The table.Columns.Count returns the actually number of columns. Somehow when it converts into a DataView, it is only returning 1 column.
//From class file
[Code]....
//From webform

In this example, I want to hide the ID column.
I have a gridview with bound fields and a templateField that receives data from a submit button which, depending upon the selected object, i.e. dropdown 1, 2, or 3, return a result set. The gridview also has a checkbox column which is used as a marker to determinie the rows to be added to and existing table. If a user selects multiple row, those rows are written to the database. Everything works.
Now, I need to add additional functionality to the gridview:
Upon selecting the checkbox, programmatically the accompanying row must become editable; for each row presented.
Deselected the checkbox, return the gridview row to a read-only state.
There are 14 columns, one of which is a dropdown which needs to maintain its default value.
I want to hide the select button in my grid view programmaticlly in the form startup. how to do this?
