file/exe is not the MIME type for executable files. It will most likely come through as application/octet-stream , but it depends on the browser and the client OS.
NB: Uploading executable files to the web server is rather dangerous. If you haven't configured your server properly, there's a possibility that the uploaded file could be executed on your server, which would be a major security vulnerability.

We can use imageUrl to display images in treeview. My images are stored in SQL database as images. How can we display the image from database in treeview?
|
|
|
|
|
Create a Generic handler to return the image from sql.
Here is a simple example:
Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim id As String = context.Request.QueryString("imageID")
Dim MyImage as Byte()
context.Response.ContentType = "image/png"
context.Response.BinaryWrite(MyImage)
End Sub
And your imageurl will be GenericHandler.ashx?imageID=...

foreach (GridViewRow row in GridView_pm.Rows)
{
if (row.Cells["MachineTypeNo"].Value.ToString().Equals(txt_search.Text))

GridView_pm.Rows[row.Index].DefaultCellStyle.BackColor =("yellow");
}
else
{
GridView_pm.Rows[row.Index].Visible = false;
}
I don't really sure about it..can you pls help me.

You should write the code in row data bound event of the gridview. The following code will change the value of the corresponding row to yellow color.
protected void GridView_pm_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (!String.IsNullOrWhiteSpace(txt_search.Text))
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
var rowView = e.Row.DataItem as DataRowView;
if (String.Compare(rowView["MachineTypeNo"].ToString(), txt_search.Text,true) == 0)
{
e.Row.BackColor = System.Drawing.Color.Yellow;
}
else
{
e.Row.BackColor = System.Drawing.Color.White;
}
}
}
}
Thanks & Regards

Simple, it submits your data. The "another page" would be the page where your form has to land after submission. Preventing the user from submitting a form via Enter key, is a bad UX, in my opinion. User would want to use keyboard for the submission process and you would be preventing him from doing so.
I have never used ASP.NET Web Forms, but I do know that even that form gets translated to HTML while rendering, so you can control that via JavaScript. Following script would suffice.
$('input[type="text"]').keydown(function (e) {
if(e.which == 13) {
return false;
}
});
This would do the trick for you, but I would suggest that you do not do so. Let user submit the form using Enter key.

Thank you soo much for your kind answer.
what I actually mean is I created a search button. when I search for the result and press on ENTER, its going to default page. when I manually click on search button its showing the result.

We can't say from what you've posted. When you press enter in a textbox the first button of the form is clicked. So you'll need to find the first button on your form and try and work out from that what is happening. It could be clicking that button is activating js or something, we don't know.

I tried that too, its work. Now the problem is I have 3 buttons in 1 panel. There are search, submit and log out. for the submit button I created as once insert data and click on submit button it will go to another page but when I use defaultbutton its remaining on the same page. because of that I did not use defaultbutton in panel.
Thank you

HI,
I want to know that,
What is the important of ISPostBack in asp.net???
Can AnyOne help???

IsPostBack is a property by which you can check that is your page is loading first time or postbacking.
In ASP.NET application every event (like clicking a button) causing postback of same page. So the code block written in the page load will execute every time.
If you does not want to execute it everytime then enclose that code block with a if(!IsPostBack){}.

HI,
IQuote: IsPostBack is a Page level property, that can be used to determine whether the page is being loaded in response to a client postback, or if it is being loaded and accessed for the first time.
example.
if(!ispostback){
}
else
{
}
When page response very first time then it go into if condition, after that your else statement will call always.
hi
|
|
|
|
|
This property is used to restrict the postback of page every time unnecessarily.
check like below in you code.
if(!IsPostback)
{
//this is your first visit.
}
else
{
//this is not your first visit.
}
