View 3 Replies i need to show images from url wich i have in my behind code. For example i have listview control :
<asp:ListView ID="ListView1" runat="server">
I'm trying to show images that come from a sql query into a GridView column, the problem is that the best solution found in the web searches the database twice for each row.
This solution says that we have to first create a handler (ImageHandler.ashx),
It will receive the ID of the row that contains the image, and then query the database with that ID.
Then it will finally perform something like "context.Response.BinaryWrite((byte[])dReader["Photo"]);" (in this case the handler uses a DataReader, I guess we could use another approach)
We also have to declare the image column in the markup as:
<asp:TemplateField HeaderText="Image">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ImageHandler.ashx?ID=" + Eval("ID")%>' />
</ItemTemplate>
</asp:TemplateField>
The problem is that, the Grid is bound to a SqlDataSource with a SelectCommand like: "Select ID, Name, Photo FROM Employees", that is already querying the database, then the GridView will execute the handler with the ID in it's query string, so the handler will query the database again for the same row, to extract the image.
Isn't there a way to send the image to the handler, so that it only performs the instruction "context.Response.BinaryWrite..." without having to query the database again?
i have the following scenario, i have a column of a gridview that shows me a text telling me is the user is allowed or not to access to some page, but now i just showing allow and deny, but i wanna show images that represent me the action, how can i do that?
View 3 RepliesI 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 have a gridview with hyperlink button in every row. Gridview is bind with some datasource.
Just what i want to do that when user click on hyperlink on particular row hyperlink button it should download a file.
The files are going to be saved daily in a share folder.
Secondly, I don't want to give user an option to open that file, means when user clicks hyperlink a dialog box should appear with open button.
how to find particular file as per date from share folder and download.
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 currently learning vb.net with sql. I have two textboxes (txtValue and txtText) , a dropdownlist (ddl1) and save button (btnAdd).

I have a folder in my CMS (ektron) which has 95 entries.The public site is only showing 50 rows. Is there something I need to do to the GridView control to show the other 45 entries?
View 2 RepliesI have some data displayed in GridView and there are multiple (repeat) entires.
There are about 20 rows of the same data, but I only want to display 1 row.
I know can amend PageSize="1" but then it shows multiple pages which I also don't want.
The multiple rows - are all of the exact same data - but it should only appear once!
I am trying to make the colors different for every line, so lets say one line white and the next light grey. I tried it in the gridview usingbut it has no effect on the display! The lines are all white! Only formatting to work is the header formatting.For CSS, I have
<RowStyle
CssClass="gridRow"
/>
<HeaderStyle
CssClass="gridHeaderSort"
/>

I have an image button on my gridview in one column, and in the next column, I have a nested gridview. What I am looking to do, is to use my image button as a way to show and hide my nested gridview. I do not want to use JavaScript, because my page already uses a great deal of JavaScript. Therefore, I want to use code behind on the button, this is what I have done so far:
ImageButton b = (Button)sender;
GridViewRow row = (GridViewRow)b.NamingContainer;
if (row != null) {
int rowIndex = row.RowIndex;
How do I use my selected row index to call the nested gridview to be visible and not visible?
In the following code i have to continuing showing the rows of the gridview as links. For example: the user will click on a customer and will see more detailed information.
protected void Button1_Click(object sender, EventArgs e)
{
//List<Customer> customersresult = new List<Customer>(); does not match the type here
CustomerWebServiceClient.Customer[] cust;
CustomerWebServiceClient.CustomerWebService client = new CustomerWebServiceClient.CustomerWebService();
cust = client.GetCustomerContract(TextBox1.Text); //coming across now..
//if (cust.va) validate if there is data
GridView1.DataSource = cust;
GridView1.DataBind();
}
// this is showing the gridview with the data coming. What would be next steps to show the rows as hyperlinks.
