Question

See more:

I have one checkedlistbox and datagridview, i want to select multiple items from checkedlistbox and the corresponding data need to fetch from database and display in datagridview.

It is working absolutely correct when i select one of the item from checkedlistbox, when i select two item then it shows only latest item selected values.

What I have tried:

C#

for (int j = 0; j <= i - 1; j++)
{
    string s = "select * from Final where Assigrp ='" + checkedListBox2.CheckedItems[j].ToString() + "'";
    sda = new SqlDataAdapter(s, con);
    ds = new DataSet();
    SqlCommandBuilder scb = new SqlCommandBuilder(sda);
    sda.Fill(ds, "Final");
    bsource.DataSource = ds.Tables["Final"];
    dataGridView1.DataSource = bsource;

}

Yes... you need to add all of the selected items to your query if that is what you want to do.

I need to design like
example:
Suppose if i selected "ABC" from checkedlistbox corresponding data fetch from database and display in datagridview, if i select "ABC" and "XYZ" it should fetch ABC and XYZ data from database and display in datagridview..

And if i unchecked "ABC", ABC data should remove from datagridview .

Hope my question is clear...

Your sql WHERE is getting a single item. Use WHERE Assigrp IN () and build your list of ids that way.

But for loop is taking only one value and display that in datagridview..
If i use Where Assigrp IN () it is showing same result..
And if i remove for loop and use Where Assigrp IN () it is not showing data in datagridview.

Use your loop to build a list of IDs and then call your sql one time using the WHERE IN () statement.

I tried below code to store checkeditems, the below code is storing checked items from checkedlistbox but my items are stored in different rows not in single row in table (database).

can you please help me to search items row by row..

string str = "";
if ( checkedListBox1.CheckedItems.Count > 0)
{
for (int i = 0; i < checkedListBox1.CheckedItems.Count; i++)
{
str += checkedListBox2.CheckedItems[i].ToString();
}
}

Solution 2

try this

C#

string where = "";
           foreach (object item in checkedListBox1.CheckedItems)
               where += string.Format("'{0}',", item);
           where = where.TrimEnd(',');
           string query = "select * from Final where Assigrp in ({0})";
           string s = string.Format(query, where);
           sda = new SqlDataAdapter(s, con);
