Data Controls :: Delete File Saved In Database Using GridView
Feb 26, 2014
When I am creating a new form, I am inserting "RequestId" of particular form in Textbox as well as uploading multiple file (that comes in Gridview)and on save button click, those gridview multiple files with "RequestId" are saved in Database as below:
Id Request Id File Name
1 12 Abc.jpg
2 12 Xyz.doc
3 12 Pqr.png
4 11 Abc.xls
5 11 aa.jpg
NOTE: Auto increment of "Id" is true.
Now, I want that If I delete any file from the Gridview(which has all uploaded files), I want that file to be deleted from database table also.Currently on Deleting file from Gridview, files from "Folder" are deleted not from Database.

I am using a bound gridview in ASP.NET 2.0. The gridview has the ability to edit/update and insert rows. One of the columns holds a number which represents a percentage. What I cannot figure out is how to ensure that all the rows in the gridview total 100% before being able to send the updates or newly inserted data to the database.
For example say there are 5 rows in the gridview, each row has 20% stored in the column so it adds up to 100% which is fine, the data is updated/inserted in the database. But say each row only had 15% totalling 75%, the user should not be able to send the updated/inserted data to the database until either they add a new row with a percentage of 25 or they edit the other rows for a cumulative total of 100%
I am not familiar with javascript or AJAX

In my MySql i am having my data field as longblob i would like to get the content in that file so i have written my code as follows
This is what i am doing before inserting
string filePath = Server.MapPath("AchTemplates/genACH.txt");
string filename = Path.GetFileName(filePath);
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
Byte[] bytes = br.ReadBytes((Int32)fs.Length);
br.Close();
fs.Close();
string strQuery = "insert into tblFiles(FName,FData) values (@_FName, @_FData)";
MySqlCommand cmd = new MySqlCommand(strQuery);
cmd.Parameters.Add("@_FName", MySqlDbType.VarChar).Value = filename;
cmd.Parameters.Add("@_FData", MySqlDbType.LongBlob).Value = bytes;
InsertUpdateData(cmd);
//Get Data
private void download(DataTable dt)
{
Byte[] bytes = (Byte[])dt.Rows[0]["FData"];
Response.Buffer = true;
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = dt.Rows[0]["ContentType"].ToString();
Response.AddHeader("content-disposition", "attachment;filename="
+ dt.Rows[0]["Name"].ToString());
Response.BinaryWrite(bytes);
Response.Flush();

I got a table in a formview where i placed lots of textboxes and dropdownlists inside the table because I need these textboxes and dropdownlists on a background image.
the data on textboxes and dropdownlists that are inside the table is unable to be saved into the database when i pressed the "submit" button. Other textboxes and dropdownlists that are not inside the table work fine. Here are the HTML code for the table:
<asp:Table ID="Table1" runat="server" BackImageUrl="~/images/DRAWING.jpg">

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?

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"

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'.
