Hi Rahim, First of all thanks for such a code,because i researched the entire google but found no single code for this ins,upd & del.
Now i just have a doubt,i used part of ur code to do just a delete opr in i update the database,it keeps on giving the same error that,”Object reference not set to instance of an object. Am getting mad trying alternatives for this error for 2 help resolve.
here it is: Hi, I was designed a windows application form named as this form my issue the name of companyname combobox is there if i choose any companyname name from combobox(cmb_companyname)has to display the remaining textboxes.i will display my tables here.
Tbl_report1 columns: Invoiceno,particulars,quantity,perprice,amount,invoicedate,ondate,invoiceid,orderno Tbl_report2 columns: Compname,compaddress,invoiceno(primarykey),orderno,ondate,invoicedate,amountstatus,netamount,netvat,tamount Tbl_customer columns: Custid,custname,custaddress,custcity,custstate,custstdcode,custphoneno,custmobileno in my form I am having these fields like I mentioned above two issue is if I select the compname it should display the remaining loading only companynames I wrote the code is below.
I wnt to display Admision no with checked box’s and checked means Present,unchecked means to do These values are will be directly insert aswell as update . for eg: user enter name in textbox and corresponding to dis textbox value related rows are selected and data is fetch in grid view.. Update(data Table); this will require update command text .. Now how should i write the insert command to insert into one table from the Data grid values. can we add a column in sqlserver database at run time using datagridview.
I could not figure the Parameters for that Insert commnad Can you please let me know the syntax for the Insert and Update commands when we use multiple tables in the select to show the data in the Datagrid. like if we add a col in data gridview at runtime it must reflect the changes in sql server database’ table. code that i used to add col in datagrid at run time..
In case you are adding row by row, then clear the rows of datagridview first in the function How we can access the entry’s in another system using LAN while running software in both systems. i want to add, delete, update in my C# forms through DLL… I have 5 tables and one datagridview , which display the information from 5 different tables, now user is allowed add/update/delete opration in the grid with new information.Tags: Adult Dating, affair dating, sex dating
