I am creating a small application using vb.net 2008 and sql server.I want to create a search form .When i click in the SearchToolStripButton
in all forms the 'Search' form will be loaded with the data from the header table into a grid.How to write code for the following

1)When i double click in one row in the grid of search window i want to return those data to the corresponding forms and i want to edit there.
After i select one row in grid in the search form and click OK button i want to return those data to the corresponding forms.

Kindly do the needful.

The easiest way would be to pass from the search form to the edit form a datatable as a parameter when you load it and have the edit form on load populate the appropriate fields from the datatable.

dear adam_k

Can u kindly provide the code to be written in search form & edit form

hello ajkva !
if my main form has a txtUserID , txtUsername , and i want to search them by using an other form , then i have to take a new form and place a grid on it and also take bindingsource component , now code this on the load event of the searching form

dim mycon as new sqlconnection("connection string")
dim ds as new dataset
dim da as new dataadapter("select userid , username from users",mycon) 
bindingsource1.datasource = ds.table("user")
datagridview1.datasource = bindingsource1

by using this code , on the load event of the form the datagrid is populated with records , then what u have to do is to code on the keypress event and on the double click event of the grid ,
now first we have to code for the double click event of the grid , but make sure before coding , that selection property of ur grid is set to row selection
now place this code on the double click event of the grid

form1.txtuserid.text = datagridview1.item("userid",datagridview1.currentrow.index)
form1.txtusername.text =datagridview1.item("username",datagridview1.currentrow.index)

after this when u double click on the grid , ur txtuserid and txtusername is populated , and ur selection form is closed , now move toward the second step , we have to code for the keypress of the grid ,

if e.keychar= chr(keys.enter) then 
form1.txtuserid.text = datagridview1.item("userid",datagridview1.currentrow.index-1)
form1.txtusername.text =datagridview1.item("username",datagridview1.currentrow.index-1).value.tostring

after all this , ur program will work perfectly
hope this will helps u :)

Thanks Waqas Aslam

The code was working fine,But my serach should work for all forms instead of 'USER' form.How to write code in that scenario.

hello ajkva !

u have to declare module and then declare some global variables so that only a single form can is used for searching for two form User and Product.for example

public UserForm as boolean 
public ProductForm as boolean

then where ever u want to call the searching form then make the value of the boolean variable true ,and write the following code in the load event of the searching form.\

if UserForm = true then 
userSearching() ' this sub is for user searching
if ProductForm = true then 
ProductSearching()' this sub is for Product searching

and then put all the previous coding according to ur requirement .

Hope this will helps u
