I want to update all rows of a GridView one time by clicking one button:
aspx:
</asp:ObjectDataSource>
<asp:ListBox ID="ListBoxRoles" runat="server" DataSourceID="ObjectDataSourceAllRoles"
AutoPostBack="true" DataTextField="RoleName" DataValueField="RoleID"
OnSelectedIndexChanged="ListBoxRoles_SelectedIndexChanged">
</asp:ListBox>
<asp:ObjectDataSource ID="ObjectDataSourceRolePermissions" runat="server"
TypeName="RolePermission" SelectMethod="GetRolePermissionByRoleID"
UpdateMethod="UpdateRolePermission">
<SelectParameters>
<asp:ControlParameter ControlID="ListBoxRoles" Name="RoleID" PropertyName="SelectedValue"
Type="String" />
</SelectParameters>
<UpdateParameters>
<asp:ControlParameter ControlID="ListBoxRoles" Name="RoleID" PropertyName="SelectedValue"
Type="String" />
</UpdateParameters>
</asp:ObjectDataSource>
<asp:GridView ID="GridViewRolePermission" SkinID="GridViewSecurity" runat="server" style="width: 100%;"
HeaderStyle-Height="50" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="ObjectDataSourceRolePermissions">
<Columns>
<asp:BoundField ItemStyle-HorizontalAlign="Center" DataField="PermissionName" SortExpression="PermissionName" />
<asp:TemplateField ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="CheckBoxRead" runat="server" Checked='<%#Bind("Read") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="CheckBoxUpdate" runat="server" Checked='<%#Bind("Update") %>' />
</ItemTemplate>
</asp:TemplateField>
</asp:GridView>
<asp:Button runat="server" ID="ButtonUpdateRolePermissions" Text="Save" OnClick="ButtonUpdateRolePermissions_Click" />
I want to update all rows of the gridview once the ButtonUpdateRolePermissions clicked.
I tried:
protected void ButtonupdateRolePermissions_Click(object sender, EventArgs e)
{
foreach(GridViewRow RolePermission in this.GridViewRolePermission.Rows)
{
this.ObjectDataSourceRolePermissions.Update();
}
}
but the update method not take Update and Read fields into consideration.

I made a gridview table for Projects which has values ProjectName, ClientID, ProjectLeader, StartDate and all the employees that work on that Project. Since i cant fit all the employees that work on a single project inside a small table i made a button inside that column that redirects you to another page where you can see table with all the employees. The employees are in another table in sql and i made third table which connects Projects and employees and it only contains ProjectID and EmployeeID. I have a button inside every row but i cant find a way how to make in code behind so that it takes the id of that project and prints on another page only employees that are working on that project.
public partial class Project : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void EmployeesOpen_Click(object sender, EventArgs e)
{
Response.Redirect("Employees_On_Project.aspx");
}
}

I have a DetailsView and a SqlDataSource as below. The NotesTB and the NameTB are not null in the code behind but are not retaining the new values entered in. They are returning the old values binded originally. I have searched the internet and can not find the reason for this and it is perplexing me.

My code behind is as follows
protected void PhotoDetailsDV_ItemUpdating1(object sender, DetailsViewUpdateEventArgs e)
{
TextBox NameTB = (TextBox) PhotoDetailsDV.FindControl("NameTB");
TextBox NotesTB = (TextBox) PhotoDetailsDV.FindControl("NotesTB");
e.NewValues["Notes"] = NotesTB.Text;//here NotesTB.Text is "" even when something is entered or it is the old value
e.NewValues["Name"] = NameTB.Text;//here NameTB.Text is "" even when something is entered or it is the old value
}
the code your bind data to your detailview, do you use a not is postback condition to make sure it will not re-bind the data after postback?

here is my redirect page control
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
Response.Redirect("~/redirect.aspx?view=" + e.CommandArgument);
}
Now problem is when I click edit it redirect me to another while it is suppose to edit the record in same page.
Change your Row_Command to this
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName.ToString() == "view")
{
Response.Redirect("~/redirect.aspx?view=" + e.CommandArgument);
}
}
I would recommend using a link when you need a link, you don't need to do postback to "redirect" the user:
<asp:TemplateField HeaderText="Key#" InsertVisible="False" SortExpression="issue_id">
<EditItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("issue_id") %>'></asp:Label>
</EditItemTemplate>
<ItemTemplate>
<a href='redirect.aspx?view=<%# Eval("issue_id") %>'><%# Eval("issue_id") %></a>
</ItemTemplate>
</asp:TemplateField>

And the update function itself.
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string s = GridView1.DataKeys[e.RowIndex].Value.ToString();
Label RID = GridView1.Rows[e.RowIndex].FindControl("RID") as Label;
TextBox SHORT_DESCRIPTION = GridView1.Rows[e.RowIndex].FindControl("SHORT_DESCRIPTION") as TextBox;
TextBox DESCRIPTION = GridView1.Rows[e.RowIndex].FindControl("DESCRIPTION") as TextBox;
String UpdateQuery = string.Format("UPDATE TAXONOMIES SET SHORT_DESCRIPTION='{0}', DESCRIPTION='{1}' WHERE RID = {2}", SHORT_DESCRIPTION.Text, DESCRIPTION.Text, Convert.ToInt32(RID.Text));
GridView1.EditIndex = -1;
BindGridData(UpdateQuery);
}
If I put a breakpoint and look at the value, I can see that is is not the newly typed in value. I'm not sure what is going on.
I think the problem is you are binding you grid on the page-load event.
try binding it in if (!IsPostBack)
Example
private void Page_Load()
{
if (!IsPostBack)
{
//bind your grid here.
}
}
use this code
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" DataSourceID="SqlDataSource1">
<Columns>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="id" HeaderText="id" ReadOnly="True"
SortExpression="id" />
<asp:BoundField DataField="regGroupID" HeaderText="regGroupID"
SortExpression="regGroupID" />
<asp:BoundField DataField="amountReceived" HeaderText="amountReceived"
SortExpression="amountReceived" />
<asp:BoundField DataField="other" HeaderText="other" SortExpression="other" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Table]"
UpdateCommand="UPDATE [Table] SET [regGroupID] = #regGroupID, [amountReceived] = #amountReceived, [other] = #other WHERE [id] = #id">
<DeleteParameters>
<asp:Parameter Name="id" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="regGroupID" Type="Int32" />
<asp:Parameter Name="amountReceived" Type="Decimal" />
<asp:Parameter Name="other" Type="String" />
<asp:Parameter Name="id" Type="Int32" />
</UpdateParameters>
</asp:SqlDataSource>
here I set id as the primary key
table structure is
Try changing the Eval to Bind. Eval is read-only so you can't actually update the value.
