Error : Meta data is not found

2011-08-20T06:09:00.000-07:00

I got this error when I was working with Dev Express Reporting Tool. I investigated why I am getting this run time error.

Then I came to know that actually corresponding dll is missing. I checked on Application Reference list and GAC list for the dll for which meta data is not found.

I surprisingly notice targeted dll was both place. Then why I am missing the dll? To solve the problem, I simply set copy to local to true.

I got the problem fixed. Aha great release! I am very glad to share my experience in my blog.

var loDataTable = new DataTable();
var loDataColumn = new DataColumn("Eval", typeof(double), expression);
loDataTable.Columns.Add(loDataColumn);
loDataTable.Rows.Add(0);
return (double)(loDataTable.Rows[0]["Eval"]);

Set Focus Controls into a lengthy Page

2009-07-07T22:45:00.000-07:00

Page scroll issues.
For example: If a lengthy page having a dropdown list with AutoPostBack = true at bottom of page. After the selection page gets reloaded and focus will be on top of the page. User needs to again scroll down the page for next key in. Here a sample solution for help...

public void SetFocus(Page sPage)
{
string[] sCtrl = null;
string sCtrlId = null;
Control sCtrlFound = default(Control);
string sCtrlClientId = null;
string sScript = null;

sCtrl = sPage.Request.Form.GetValues("__EVENTTARGET");
if ((sCtrl != null))
{
sCtrlId = sCtrl[0];
sCtrlFound = sPage.FindControl(sCtrlId);
if ((sCtrlFound != null))
{
sCtrlClientId = sCtrlFound.ClientID;
sScript = "";
sPage.ClientScript.RegisterStartupScript(typeof(string), "controlFocus", sScript);
}
}
}

Call this function on page load

Example: SetFocus(this);

This will set focus on last used dropdown list.
