How To Display Error Message In C
c# datafilter results in no colums?
I have the following
[code]
DataView incidentList = (DataView)
incidentDataSource.Select(DataSourceSelectArguments.Empty);
incidentList.RowFilter = "CustomerID= '" + CustomerID + "'";
DataRowView row = (DataRowView)incidentList[0];
[code]
now I need to do work only if there are results found, in there are not then I will display and error message that the customer id was not found.
how would I do that?
so i need to do something like
if (the results are nul)
{
display error
}
else
{
...do work
}
thanks
The DataView has a Count property which will have the number of records contained within the DataView. Just check this value.

The Message $3.95 The ancient hymns, poems, and prayers found in the Psalms teach us how to communicate with God. As Eugene Peterson writes, this book "gives us a language adequate for responding to the God who speaks to us."

Solomon SHABUOTH The Essence of Judaism Abraham E Abramowitz The Chosen People C. E. Hillel Kauvar The Jew and Idealism Felix A. Levy PREFACE TN presenting this volume to the attention of the spir- itual and lay leadership of all denominations, it is the hope of the editor and compiler that it will be generally regarded as more than a merecollection of sermons and religious essays. Religiously, American Jewry is divided into three distinct camps ORTHODOX, CONSERVATIVE, and REFORM, and so tautly drawn are the differences in the minds of the adherents of the respective shades of belief that too frequently have animosities, bickerings and misunderstandings flared forth. And oddly enough, in the majority of cases the most militant protagonists have been woefully ignorant of the essential differences. Nor is it any great consolation to point out that all mistaken notions to the contrary notwithstanding, the Christian religious world is even more hopelessly di vided, there being over two hundred Christian varie ties in the United States alone at the present time. For, as Professor Conrad Henry Moehlman in his excellent book, Christian and Jew, points out, The real issue in the Western world today is not whether Catholic ism, Protestantism, or Judaism will survive, but whether religion will prosper. In Russia, Germany, Spain, Mexico everywhere the foes of religion are gathering their forces to stamp out a belief in God. How essential, therefore, is it that Judaism which gave the concept of God to man, shall present a united front in its stand against this on slaught In the face of innumerable discrimination |
