Actually it is totally related on how the data is sent to the Outlook from the browser. The process is invoked from the Browser and depends on the browser itself.
Rather than doing this, I think the better way would be to send email from your web interface, not using mailto in your case.

I've got large images in DB and after GridView control is bound to DataSet the GridView.ImageField column becomes very large. How to restrict the max size of the GridView.ImageField column?

Have you considered storing and using a thumbnail of the image?
|
|
|
|
|
I can store the thumbnail of the image in addition.
But GridView.ImageField accepts only ImageUrl as a bound control. How can I pass to it say jpeg thumbnail saved in db?
I tried to bound to its url original jpeg stored in db, but it got the error while I called DataBind().

I setup Control style to certain width and height and it worked.
Can we set individual rows ImageField sizes so that they display images proportionally, not stretched to fixed NxM predefined size?

You means each and every image field should have different size and Image size will be the same of image field ?
|
|
|
|
|
No, I meant images of different sizes and width/height ratios would be shrinked to ImageField fixed size retaining aspect ratio.
As currently all images resized without preservation of aspect ratio, just interpolated to NxM.

See this is my code:
I hope it will work fine.

Are you creating/loading your DropDownList control dynamically. Whenever the postback is happening your DropDownList is re-initialized. Move your creating/loading of the DropDownList into !IsPostback check.
If you could post the code used in the UserControl, it would be easier for answering.

Thanks for ur time..
this is the usercontrol which is placed in the placeholder ...
my issue is (!postback) is not working in user control...
namespace IndiaInfoline.Markets.Derivatives
{
public partial class NiftySummary_Inner : System.Web.UI.UserControl
{
DerivativeDAL DerObj = new DerivativeDAL();
DataSet DS = new DataSet();
public string InsSymbol, InstName, Symbol;
static int flag = 0;
protected void Page_Load(object sender, EventArgs e)
{
//if (flag == 0)
//{
// Fillselection(DropDownSymbol.SelectedValue);
// flag = 1;
//}
// Fillselection(DropDownSymbol.SelectedValue);
}
protected void Page_init(object sender, EventArgs e)
{
Fillselection(DropDownSymbol.SelectedValue);
}
protected void DropDownSymbol_SelectedIndexChanged1(object sender, EventArgs e)
{
Fillselection(DropDownSymbol.SelectedValue);
}
public void Fillselection(string ddlselectedval)
{
InsSymbol = ddlselectedval;
string[] strParts = InsSymbol.Split(new char[] { '|' });
InstName = strParts[0];
if (InstName == null)
InstName = "";
if (strParts.Length > 1)
Symbol = strParts[1];
else
Symbol = "";
DS = DerObj.Deriv_GainLoseHiLo(InstName, Symbol, "", "MW");
if (DS.Tables[0].Rows.Count > 0)
{
SummGrid.DataSource = DS;
SummGrid.DataBind();
NoDataFound.Visible = false;
}
else
{
NoDataFound.Visible = true;
}
}
}
}

Here is the culprit. All postback actions will go thru the complete Page Life cycle. Change your code to following.
protected void Page_init(object sender, EventArgs e)
{
if (!Page.IsPostback)
Fillselection(DropDownSymbol.SelectedValue);
}
I hope, this would solve your problem.
Mark it as "Good Answer" if it is helpful.

Yes, You can do it easily using AJAX Timer.
Have a look: Reference[^]

|
|

Use Ajax Timer Control.
and trigger Asynchronous callback on timer tick(I-e ) update the panel
Like this
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div >
<asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick">
</asp:Timer>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
</asp:UpdatePanel>
