The delete link on my gridview deletes the previous row instead of selected row....Also, it doesnot delete the already existing rows. When I add new rows and try to delete them then my delete works that too incorrectly.

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="photoID"
Is there a way based on the current user that when the page loads that the Delete option on the gridview is disabled?

I do also have a checkbox boolean field.
If checkbox1 is checked then I want to hide or disabled the delete button.

I am still at the elementary stages of Linq To Sql and Entities usage. I started practicing MVC developement by following the NerdDinner tutorial here at asp.net, and I back myself up with fully developed NerdDinner sample (1.0 -- still on VS2008). I am also at the first half of the NerdDinner tutorial (I think -- maybe I'm further along) - so far I have gotten up to the Delete View. In the fully developed sample I noted that it uses ascx file (which I guess I will find out if the tutorial also will use
ascx files down the road). My sample app, which I am developing from the tutorial, seems to work OK so far. My issue is that I am not clear how the Delete mechanism works. In the DinnerRepository.cs I have this code (from the tutorial):
[code]....
It looks like a dinner object is being passed to these mechanisms and the delete occurs based on a row ID value. But what if I wanted to delete multiple rows - say where ID between 15 and 20 - how to go about this? I was looking for a Delete statement but am not finding it either in what I have developed so far from my tutorial sample or from the fully developed sample. How can I control Deletes in MVC?
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 am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.
I have created a page with a gridview in asp.net that displays the records of a database table and allows users to delete checked records by clicking on a delete button. After I delete a record and I try to refresh the page from the browser (I am using mozilla)I get the follow message:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
and if I click resend another record is deleted automatically. Even though I am reloading the gridview after the deletion the application executes again the onclick event of the delete button is executed and the gridview things that there is a checkedbox selected so the code executes my delete function again.
Is there any way to get rid of these behavior. I have been trying quit a few things but nothing works for me.
I have a Timer and a GridView who pulls info from the database every X seconds.Every time I query the database the field 'Comments' is replaced with whatever is on the database (since it's bound to it). I'd like to keep my previous value and keep adding into my Label the subsequent values queried from the database.
For instance, first time I query I get a value of "1" in the Gridview. Now someone changes the database row and next time I query it I have a value of "2". Well, I would like to concatenate the last value queried with the previous one and so on.
So at this point the GridView should show "1" and "2". Here is the piece of code I am talking about:
<asp:TemplateField HeaderText="Comments" SortExpression="Comments">
<ItemTemplate>
<asp:Label ID="lblComments" runat="server" Text='<%# Bind("Comments") %>' />
</ItemTemplate>
</asp:TemplateField>
How do I achieve this goal?
I am using a Gridview binded to a LinqDataSource that represents a database view. The gridview paging is enabled. When navigating from page 1 to page 2, it displays the right count of rows in this page (assume pagesize is 10 and page 2 should have 4 rows only to have total of 14 rows in the view; the datasource), however, it populates wrong data (from the previous page). On the contrary, when I disable paging, everything works ok.

I want to show First , Next , Previous , Last Buttons all the time in gridview if i am last page then disabling the Images. But i want dont want to hide the images.
View 2 RepliesI have a gridview, getting data from sql server, there is an Edit link to get the detailed information for example, for a user from database.
this link open a new page with detailed information and when I click the updated button,I want to go back to the same page with that users informaton.
I set the page size to 10, it means I can see only 10 users per page,and if I click the edit link on page 25,and update the users info, I want to go back to page 25.
Should I use viewstate or gridview has any commnad to go back to the same page? the code is written in ASP.net C# sqlserver,
I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.
View 8 RepliesI have a page where I am displaying a series of 10 items that are each links. This data is fed from a database. I need to add a previous and next function to this page but I cannot use any of the data controls in ASP.NET. I need to grind this out manually.
The page iterates through a recordset of up to 10 records and formats the data and inserts it into the innerHTML of a div on the page. What would be a good method here for implementing a previous and next function without using the GridView or other data bound controls?
I have a question about using a linkbutton. I have 5 link buttons. One is a DayLink, MonthLink, WeekLink. One PreviousLink and One NextLink. How can I get the previous and next buttons to correspond with what page I am on. So say I am looking at the calendar in days. And I'm on Thursday 2/18/10, and I want that next link button to go to Friday 2/19/10. But also need it to go to the next week or month, depending on how i'm looking at the calender. So I need one linkbutton to be able to do multiple steps.

I have a gridview control on my page that lists records and sorts them according to the most recent to the oldest record.

I'd like there to be the word 'Delete' next to the first record only.
