I have a page which as been working just fine for months, that is simply pulling SQL data to a dataset, and on the RowDataBound event, I am adding a new cell to the row, a hyperlink to another page which is based on text data in certain columns of the row. All of that is fine. This week I have been trying to figure out a way to add one more column based on a user request. They would like to have a checkbox column and a button that performs an act with each of the checked items. This value doesn't need to be stored anywhere, and is only used in the session to determine what rows this action is taken against.
I am a noob to asp.net, usually spending time in Winform apps, but trying to help someone out by providing web page access to some data. I have scoured the pages trying to sort out whether I need to rewrite the page and data access in some way but there seems to be many many different ways people have solved similar problems. I think I have gotten really close a few times but either end up with a checkbox which I cannot get the value for (by adding cells in the same code that adds the hyperlink), to adding a templatefield. In this attempt what happens is that if I keep autogeneratecolumns=true then my databinding blasts over the templatefields and if I set it to false, nothing happens on databinding..
I really apologize to the many advanced users who
i have an application in Vs. C# i have gridview with big data so its not in graphical mode so i want to paging in gridview . is there any command in C# to enter paging in gridview ?
I have a GridView. The data is displayed in TemplateFields: textboxes and dropdown lists. E.g. rows 5 and 7
have certain values selected in the dropdown lists of column 1. After I
use filtering, still the same values are selected in rows 5 and 7,
though because of filtering, different records are displayed in those
rows. The same thing happens with TextBoxes.
Could you tell me how I could avoid preserving data after postback?
I tried to disable ViewState of the GridView or of the dropdown lists or textboxes, but that didn't help.
Hello, i have some GridView Using LinqDataSource1 (GridView1). i want the gridview to update everytime the user make something on page so im using GridView.DataBind() in the Page_Load method on code behaind (isPostBack statement) and its working fine!!! (the user make something on view1 on Multiview and then jump to view2 to see the gridview) the problem is, when the user want to edit some row in the gridview (using the gridview commands) the data dont update!! he can only delete rows. when im removing the isPostBack statement its working and the user can update and delete but i need the isPostBack so the gridview will update his rows. any idea?????
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
CellPadding="4" DataKeyNames="userFileId" DataSourceID="LinqDataSource1"
ForeColor="#333333" GridLines="None" Width="540px" Font-Names="Arial" Font-Size="X-Small">
<RowStyle BackColor="#EFF3FB" />
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
<asp:BoundField DataField="fileName" HeaderText="?? ?????"
I am assigning DataKeyNames, i need to call my encryption function before passing the value for DataKeyNames. How i can do this.
Here is my code :
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" BackColor="White"
BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3"
I need something like DataKeyNames="MyClass.Encrypt("ID")"
I am trying to avoid code behind use. Please give me some tips if it can be done in .aspx page?
I have a ASP.NET gridview (embedded into a DIV) with several columns. For some columns line wraps are definied and for some not(with ItemStyle.Wrap = true/false). For all columns ItemStyle.Width is set to a specific value. Now I am wondering, that there is a line wrap in a column, where ItemStyle.Wrap = false. What could be the reason for that?
I've been developing with gridviews for quite some time now. Just
recently I came across a situation that has me stumped. Here's how the
gridview has been working for me.
stored procedure from the database is called (three parameters are passed (reporttype, name, location)
data is retrieved using the SqlDataAdapter to fill a Datatable
gridview DOES NOT AUTOGENERATE COLUMNS
are created programmatically as it reads the DataTable results (headertext,
datafield, and dataformatstring are set at runtime)
Gridview triggers the databind event - and voila it works.
dilemma is this: the stored procedure (that I haven't developed) returns
a various set of columns and column order. I have one report type that
does the following:
ReportType 1: column orders returned in the following order when running
directly in SQL
col B, col C, col D, col E, col A
I run the report through my gridview, the column order is as follows:
I have a GridView that displays the sample data as following:
Category | Title | Grade
Math | Algebra | 6
Math | Geometry | 5
Math | Algebra | 4
Reading | Basic | 5
There are no duplicate records. Is it any solution to obtain values of category, book and grade of each row with checkbox marks and pass them to stored procedure parameters: ParamCategory, ParamTitle, ParamGrade for deleting process. I believe that we can get values of one specific row with checkbox mark. Any suggestions or comments how to solve are really appreciated. If possible to give me a sample codes soon, thanks in advance.
