How may I do all of this in Aspx.cs file, do I create a DataSet and set as DataSource to the GridView , and How I set the values to the columns ? Thanks !
Obs: I Also have two butons on the cells.
[Comment] - Other solution would be pass a parameterin the code below, is it possible ? I need to pass the value of a Session
回答1:
I finally found out the answer from here!
My aspx code: Here is my Select command with my Parameter @club
SelectCommand="SELECT ch.id, sit.descricao as situacao, resp.responsavel, ch.dt_cadastro, ch.previsao_termino, func.descricao as funcionalidade,
proj.descricao as projeto ,pr.id as prid, pr.prioridade, clb.clube
FROM chamados AS ch
INNER JOIN prioridades as pr ON ch.prioridade = pr.id
INNER JOIN clubes as clb ON ch.clube = clb.id
INNER JOIN responsaveis as resp ON ch.responsavel = resp.id
INNER JOIN situacoes as sit ON ch.situacao = sit.id
INNER JOIN projetos as proj ON ch.projeto = proj.id
INNER JOIN funcionalidades as func ON ch.funcionalidade = func.id WHERE situacao != 3 AND ch.clube = @club"
<SelectParameters>
<asp:Parameter Name="club" Type="String" />
</SelectParameters>
Then here is my aspx.cscode: Here I set set the value of the parameter, as it is in aspx.cs you can do anything you want to set the value...
MyDataSource.SelectParameters["club"] = new Parameter()
{
Name = "club",
DefaultValue = "2" };
Worked just perfect xD hope it can helpe someone else... Bye Guys!

You can do all of these tasks in Code behind page as well. Please refer following link for further reference.
