Get the count from the datasource you have assigned to the grid
only two letters away from being an asset

Wow I finally figured out a way to do it. This is what i used:
Protected Sub SqlDataSource1_Selected(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Selected
resultsNumberLabel.Text = e.AffectedRows.ToString & " record(s) found."
End Sub

You could find you answers at Chris Khoo post
http://www.codeproject.com/aspnet/netimageupload.asp
Based in that post i made these two functions for asp.net C#.
you must to invoice the public function. The parameters are:
MaxWidth = max Width pixels
MaxHeight = max height pixels
UrlAndFileName = the From address image
UrlAndNewFileName = the save address and new file name
Example: (600, 600, "C:\Documents and Settings\Barriosj.FMMB\Mis documentos\Mis imágenes\imagenes\73237_4611.jpg", "c:/myRedimImage.jpg")
The image is restricted by the smallest width or heigth value.
public void Redim_And_SaveImg(int MaxWidth, int MaxHeight, string UrlAndFileName, string UrlAndnewFileName)
{
// load up the image, figure out a "best fit"
// resize, and then save that new image
Bitmap OriginalBmp = (System.Drawing.Bitmap)Image.FromFile(UrlAndFileName).Clone();
Size ResizedDimensions = ObtainDim(MaxWidth, MaxHeight, ref OriginalBmp);
Bitmap NewBmp = new Bitmap(OriginalBmp, ResizedDimensions);
NewBmp.Save(UrlAndnewFileName, System.Drawing.Imaging.ImageFormat.Jpeg);
}
private static Size ObtainDim(int MaxWidth, int MaxHeight, ref Bitmap Bmp)
{
int Width;
int Height;
float Multiplier;
Height = Bmp.Height;
Width = Bmp.Width;
// this means you want to shrink
// an image that is already shrunken!
if (Height <= MaxHeight && Width <= MaxWidth)
return new Size(Width, Height);
// check to see if we can shrink it width first
Multiplier = (float)((float)MaxWidth / (float)Width);
if ((Height * Multiplier) <= MaxHeight)
{
Height = (int)(Height * Multiplier);
return new Size(MaxWidth, Height);
}
// if we can't get our max width, then use the max height
Multiplier = (float)MaxHeight / (float)Height;
Width = (int)(Width * Multiplier);
return new Size(Width, MaxHeight);
}

This you can do in OnItemDataBound event of the datagrid. There you have to check the value coming from the database and display the message accordingly..

In the OnItemDatabound(this gets executed for each and every row of the datagrid) event first you have to get the value and depending upoin it you can display the message what you want. Sample code
public void test(object sender, DataGridItemEventArgs e)<br />
{<br />
<br />
if(e.Item.ItemType==ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)<br />
{<br />
DataRowView drv = (DataRowView)e.Item.DataItem;<br />
if(drv["Yourcolumnname"].Tostring() == "0")<br />
{<br />
}<br />
else<br />
{
}<br />
}

Private Sub grdTest_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdTest.PreRender<br />
<br />
Dim item As DataGridItem<br />
<br />
For Each item In grdTest.Items<br />
item.Cells(1).Text = IIf(item.Cells(1).Text.ToUpper = "TRUE", "Yes", "NO")<br />
Next<br />
End Sub

If the data is less and not very important then you can send through querystring also.

Hello,
please give the details Difference b/w DataGrid and Dataset..
|
|
|
|
|
Dataset is a set of records which are retrieved from the database. The DataAdapter fills the data into dataset and whatever changes which are made to the dataset gets updated in the database with the help of dataadapter.
Datagrid is one of the web controls which makes use of the dataset to store data into it.
Thanks & regards,
Suresh Dayma

A dataset holds data in memory, often loaded from a dataabse
A datagrid displays data, often held in a dataset.

hi
What is wrong with this ReportPath?: /Pages/ReportViewer.aspx?/IL_User/Weekly_ConversionAppRate
When I view it from ReportServer it works, but not when I run it in reportviewer in asp.net 2.0
FYI: ReportServerUrl: http://ildevsvr02-v05/reportserver
I get the following error: The path of the item "/Pages/ReportViewer.aspx?/IL_User/Weekly_ConversionAppRate" is not valid. The path must be less than 260 characters long and must start with slash. Other restrictions apply. (rsInvalidItemPath)
thanks

how can v use object pooling concept in our application and wat is need of Object pooling in .net
|
|
|
|
|
|
k tanx but can u explain little more abt object pooling
Regards
Raja
|
|
|
|
|
an object pool is a set of initialised objects that are kept ready to use, rather than allocated and destroyed on demand. A client of the pool will request an object from the pool and perform operations on the returned object. When the client has finished with an object, it returns it to the pool, rather than destroying it.
Object pooling can offer a significant performance boost; it is most effective in situations where the cost of initializing a class instance is high, the rate of instantiation of a class is high, and the number of instantiations in use at any one time is low.
