Updating row in gridview

20-May-2020 13:17

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. How to write the connection string to that in windows application(C#). adding , deleting , updating textboxes is very simple if we write codes on buttons. user can add or update or delete the datagridview row. private void loadcompanies() But it shows the that I wrote the code in selectedindexchangedevent. private void cmb_companyname_Selected Index Changed(object sender, Event Args e) } Best, Sudheep.

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.

Could you please explain how to do this from the start.

I can’t for the life of me find a tutorial that explains this from A to Z.

I have done this kind of stuffs with vb6, has not done it with C#. the better idea is create a new function in datagridform, then shift(cut & paste) the code which you use to fill datagridview in a new function(means refactor the code to function).

Now when you close the add form call that function. I want to know how to insert/update/delete in a Multiple tables in a single datagridview. thanks thendral HI Rahim, My Name is Raman ,as per the above comments , I understand you are very good at I am new to win app, but good SQL server, Can you tell me , I Can Solve the below querdy.
