Forms Data Controls :: Code Behind Delete For Gridview - Null Value For Selected Row?

Jan 7, 2011

I have a link button that I want to function as delete. I have to do it this way because I want confirmation before allowing deletes. In my debugger, I flagged this block of code and run it line by line. For some odd reason, it thinks my selected row. Maybe I'm overlooking something? Here's my code behind source:

Forms Data Controls :: Use LinkButton Inside Gridview To Delete Selected Username

Mar 25, 2011

I have a "UserDetail" table in my "JobPost.mdf". I have a "Gridview1" showing the column from "UserDetail" table,which has a primary key "UserName". This "UserName" is originally saved using Membership class function. Now I add a "Delete" linkbutton to the GridView1. This "Delete" is not autogenerate button,I dragged inside the column itemtemplate from ToolBox. The GridView1's columns now become "Delete_LinkButton"+"UserName"(within the UserDetail table)+"City"(within the UserDetail table)+"IsAdmin"(within the UserDetail table)

What I need is that by clicking this "delete_linkButton",it will ONLY delete the entire User Entity on the same row (link by the corresponding "UserName") from the "UserDetail" table,as well as delete all information from the AspNetDB.mdf (User,Membership,UserInRole,etc). I would like to fireup a user confirm,but not mandatory. At least I am trying to make it functional in the correct way.

[Code]....

When I click "delete" on the first row, I need all the record about "ken" inside the "UserDetail" table to be removed. Meanwhile, all the record about "ken" in the AspNetDB.mdf will be gone, including UserinRole table. I am new to asp.net, so I don't know how to pass the commandargument of the "Delete_LinkButton" to the code-behind file LinkButton1_Click(object sender, EventArgs e), because I need one extra parameter "UserName". My partial code is listed below:

Forms Data Controls :: Gridview Delete Button - Running Additional Code When Pressed

Apr 28, 2010

I have a grid view with the delete option enabled. When the user clicks on delete, that entry in the database is deleted. However, each entry in my database corresponds to 2 images on the server. When that entry in the database is deleted, I also want to delete the images. (the images consist of the ID for that database entry plus "right.jpg", and "left.jpg") Is there a simple way to do this? My thoughts are that I need to run some additional code when the user clicks the delete button, but how can I trigger this code?

Forms Data Controls :: Gridview-Calculate Value Based On Formula That Varies Dependent On Selected Code In Dropdownlist?

Jul 2, 2010

GridViewDetails uses templatefields. In edittemplate I put a button called "ButtonUpdateAdjustAmount" with OnClick="Update_AdjustAmount" in the EditItemTemplate for the "Amt to be Adj" column. There is also a textbox. My user's should be able to edit the textbox, but I also want the ability to click the button and the textbox populated with the correct calculated value. The formula varies based on the "code" column which is a dropdownlist called "DropListCode".

I am fairly new to asp.net, vb, etc...so forgive my code writing. Eventually I need to also put the same functionality on the insertrow for my gridview. But first wanted to get the edit one working. I am using templatefields for all columns and the FooterTemplate to perform the Insert New Detail Line.

I can get the functionality to work for the first data row and only if I take out the If code.SelectedValue = ... line and leave 1 static formula. However that isn't going to work. If DropListCode.SelectedValue is DNR then AdjAmt should be ((q_ordered - q_received) * cost). If DropListCode. SelectedValue is OV then AdjAmt should be (RKNumber * cost). If DropListCode.SelectedValue is NB the AdjAmt should be ((q_received - q_ordered) * cost). If DropListCode.SelectedValue is DAM then AdjAmt should be (RKNumber * cost)

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?

Nov 18, 2010

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?

Forms Data Controls :: Delete Images From Folder Using Gridview Delete Link?

Feb 3, 2010

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.

Forms Data Controls :: How To Insert Delete Confirmation Dialog To Gridview Delete Button

Apr 6, 2010

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'.

Forms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?

Dec 6, 2010

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?

I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

Forms Data Controls :: Delete Selected Item From DataTable Using LINQ?

Feb 1, 2010

I have a ListView which I populate using DataTable.

In each row I have a delete button. When the user clicks on the delete, that particular row is deleted in the DataTable Table.

After I perform the delete, I want to avoid page reload just to populate the ListView with the new set of records without showing the deleted row.

I suppose LINQ is the best choice for this. But I am unable to implement it.
