tasumisra

on load of the screen or where ever you are loading the grid just before binding to the dataGrid you can loop through each row and check the condtion where Rows[0].Cells[0].tostring()=="xyz"

Hi, Why don't you use the BindingSource Filter property? For example, you can have myDataSource.Filter = "City = 'DOWNTOWN'" Here is the example from MSDN: private void PopulateDataViewAndFilter() { DataSet set1 = new DataSet(); // Some xml data to populate the DataSet with. string musicXml = "" + "" + "ColdplayX&Y" + "Dave MatthewsUnder the Table and Dreaming" + "Dave MatthewsLive at Red Rocks" + "Natalie MerchantTigerlily" + "U2How to Dismantle an Atomic Bomb" + ""; // Read the xml. StringReader reader = new StringReader(musicXml); set1.ReadXml(reader); // Get a DataView of the table contained in the dataset. DataTableCollection tables = set1.Tables; DataView view1 = new DataView(tables[0]); // Create a DataGridView control and add it to the form. DataGridView datagridview1 = new DataGridView(); datagridview1.AutoGenerateColumns = true; this.Controls.Add(datagridview1); // Create a BindingSource and set its DataSource property to // the DataView. BindingSource source1 = new BindingSource(); source1.DataSource = view1; // Set the data source for the DataGridView. datagridview1.DataSource = source1; source1.Filter = "artist = 'Dave Matthews'"; }

:wtf: are you insane? I would hate to see crap like that in a program i have to maintain...

Assuming the 1000 rows are coming from a data base, you have two options... 1) Query only the data your looking for and not everything, remember "any monkey can SELECT * FROM 2) Use a DataView to filter out the data you want to display

I have seen your answer ... but some times we can't hardcode any querry from sql command it will cost more if u need to change your condition. anyway if you have ever used WCF then in services we are binding the reader object with our business object for each row that time we can filter it out more easily...

In that case, create a stored procedure for SQL and call that in your application... problem solved :) OR Use the DataView object, i use this frequently to filter data dynamically

as mentioned use the filter option or change the query to have a where clause. but FYI. THE USE OF CAPITALS is considered shouting in forums. :-D
