Edit and Delete functionality works flawlessly in Gridview if all data is pulled ONLY FROM ONE TABLE. But pulling data from one table give you ID's instead of actual values that are stored in other tables.
After creating a usable Select statement that would pull all the correct values, my Edit and Delete functionality no longer work.
Here is code.

I want delete, edit, select items is in grid view i have to do in c# code it will reflect to database also
View 3 RepliesIn one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.
I used below code for above:
C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
[Code]....
problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:
Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"
I am new for MVC, now we are using MVC 3 Razor. I am using Webgrid with edit and delete functionality
my requirement is i want to display image instead of edit and delete Ajax.ActionLink with same functionality.
How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?
I would like to implement code to delete the selected row in the gridivew using Radiobutton .

I'm trying execute code only when FormView is in Edit mode ---but the code following line this is being executed even in read-only mode.
If formname.CurrentMode

Then
Lot of times I did edit, delete, insert in my webproject in different pages but I am very surprised that why I am not remembering the technique to do these task. Actualy I never take any course on asp.net/vb.net, what I did in my project just to take help from forum or asp.net website etc. I get a task again to make a web interface having functionality to view data and provide Edit functionality also. The other task is to click a link in the same page to open a new page with the fields of the same table to insert new record.
Q1: Is it necessary to take a dataset or I simply do it using sqlDatasource?
Q2: Could anyone give me a very basic and simple vb.net/asp.net project with all above tasks so that I will do a practice project and never miss it?
I have walked through other posts with a similar problem but I am very stuck.I am normally use Php/MySQL and am new to ASP (actually only this new client uses it and I'm trying to help them). I am trying to filter a table to only show the last 90 days of records. I found what I thought was the easy solution shown below:
FilterExpression="columnname < GETDATE() - 90"
Or, if you can modify your SQL SELECT statement
SELECT col1, col2, col3 FROM tablename WHERE col3 < GETDATE() -90
However when I added it I get this error:Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Type 'System.Web.UI.WebControls.BoundField' does not have a public property named 'FilterExpression'.I think I have added the code to the wrong place or have another file to edit but I have no clue honestly. The best I can do is show you the file I have the code to in hopes someone may know what this is. Here is the code from the file I added the solution to (my edit is bold/italics/underlined towards the bottom): And shouldn't I have some select statements somewhere like I normally do with MySQL?
<%@ Page Language="C#" MasterPageFile="~/SecureRck.master" AutoEventWireup="true"
Codebehind="Default.aspx.cs" Inherits="SecureRckWeb.Reps.Default" Title="Reps" %>
<%@ Register Assembly="schedule2" Namespace="rw" TagPrefix="cc1" %>

I'd like to print out the select statement for a SqlDataSource to see exactly what is being issued to the database. I added an OnSelecting event and the code shown below. The problem is that it's printing the variables in the select statement rather than the values assigned to those variables. How do I print out the "resolved" output so that I can see the values being passed to the database.

The code below returns a dataset that I use in a Gridview. How can I modify my select statement to format the DateEntered as a Date in gridview with no time and TimeEntered as Time in gridview without date info?

I have a formview, selecting * from friends, where [date] = getdate()
The problem is the friends table date columns datatype is datetime, i cannot make it just date.
I only want to display data if the date is the actual date, i.e. between 00:00:01 and 23:59:59
How do i select only the date for both getdate and my date column?
SelectCommand="SELECT * FROM [friends] WHERE ([date] = getDate())">
I'm struck at editing the row which is displayed after search operation being performed. I've a table that has User_ID, Name, Status. I would like to bind data and display in gridview. I've implemented a search box to search fr the name and edit the status of the person. But if I'm trying to implement edit option on the searched entry it is not working as how I needed .
<asp:Content ID="Content2" ContentPlaceHolderID="Dresses" Runat="Server">
<div>

the select statement for my gridview contains a sub select statement..that should allow users to see how many queries are associated with a particular record..how can I get the queries column to display in my grid. As it is a count and not directly bound to any field
SELECT
WardID,
ScriptID,
DateAdded,
(SELECT COUNT(scriptID) FROM query WHERE scriptID = main.scriptID) AS queries.......
I have a record in gridview contains string with special character like single quotes( ' ) etc..I've a edit button in gridview when i click on edit button of any record of Gridview then corresponding record shown to text box.
But on that time single quote looks like below ....
Before edit button click string in gridview cell, a testimonial or show consists of a person's written or spoken statement
After edit button click string in textbox, a testimonial or show consists of a person's written or spoken statement but when I click update button shows following error :
"A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$tb_comment="...f a person's written or sp...")"
What is the solution so that single quote shows as it original format as it looks in gridview cell when i click on edit button.

I've seen use an inline <asp:SqlDataSource> to bind data to a gridview when usin the delete or edit features. I, for a few reasons, use a button_click event (because depending on a selection from a radio button "list", there are specific fields/parameters to query the database). So there isn't a "Delete" or "Edit" feature of basic sqlclient controls (that I know of).
how to either use normal sqlclient controls with a gridview to handle the delete/edit features of a gridview, OR explain how I can use an inline sqldatasource in the codebehind to query the database with specific select statements and specific fields/parameters?
What I mean by different fields/parameters, is that there are radiobuttons, and depending on which is chosen, the query changes. So I can't just use the same select query and have the parameters just be "TextBox1.Text" or whatever (because I might not need that parameter since the query would be different).
I have a gridview and in my code behind i have added the edit/update functions like below
now how can i change the name of edit/delete which automatically comes ?
<asp:GridView ID="friendListGridview" runat="server" CellPadding="4"
ForeColor="#333333" GridLines="None"
AllowPaging="true" AutoGenerateColumns="false" Width="80%" AutoGenerateEditButton="True" DataKeyNames="id"
AutoGenerateDeleteButton="True" >
<Columns>
<asp:TemplateField ......
I have problem with the buttons Edit and Delete in Gridview for very long time and i really need about it. So the when i click edit i get in edit mode and when click update the values in the row i was changing disappear but only in the gridview. When check in the Database nothing happens. The delete button not works at all, i mean when click on it only refresh the table.
See how looks my page:
Now here's my code in aspx:
[Code]....
Now here's my code in cs:
[Code]....
I'm not sure if the statements not working. P.S. the cancel button works fine.
how do i edit and delete in gridview without sqldatasource commands?
