asp.net c# DetailsView DropDownList fails to Update

asp.net c# DetailsView DropDownList fails to Update - c#

I've created a DetailsView that displays data based on a selected item from a GridView. When the DetailsView is under Edit Mode, it displays dropdownlists that contain data from a SQL databind. The data displays in the dropdownlist without issue, but fails to update. All other fields succeed.
The data is bound to the drop down via OnDataBound.
The idea is to populate the SelectedValue with the current data, and populate what it can be changed to. This works without issue. It simply fails to update.
I believe it has to do with syncing the control with the "an" parameter, but am at a loss at how to do so.

Your update command appears to be part of the details view, and not part of any ObjectDataSource. Can you confirm your markup above is correct?
Edit
In your UpdateParameters group, you aren't getting the values from the controls. Try doing the following:
<UpdateParameters>
<asp:Parameter />
...snip
<asp:ControlParameter Name="an" ControlID="idOfWhateverControlHasTheUserSetValue" Type="String" />
...snip
</UpdateParameters>

I took your advice and did a little research about using the ControlParameter.
The fix was adding the following to the Update Parameters, and removing the auto-populated parameters for 'an'. Thanks for the help, Nick.
<asp:ControlParameter Name="an" ControlID="userDetails$anEditDD" PropertyName="SelectedValue" Type="String" />

Problem with InsertCommand in SqlDataSource. ERROR: System.Data.SqlClient.SqlException: 'You must declare the scalar variable'#EXPEDIENTE'.'

I am a newbie and I have recently started working developing a web application, I do not have much experience so if you are able to solve the problem and explain it in detail I would be much more than grateful. I am trying to insert in Visual Studio through a Gridview a series of data in my database. For this I have several textboxes and a dropdownlist in the FooterRow to obtain a series of data and the other data that is missing in the insert I obtain it by looking at other GridViews/querying the database. At the end, after successfully obtaining all the data I need to insert through the SqlDataSource, I am ready to insert the data with cmd.ExecuteNonQuery(); But when trying to do it I got this error: System.Data.SqlClient.SqlException: 'You must declare the scalar variable '#EXPEDIENTE'.'

I am turning crazy trying to find a solution , if anyone could help me i would be so thankful.Thank you very much in advance

i already found the problem. In the C# code i used the parameter param all the time and i needed to use param2 , param3, param4 etc.... Changed that and everything works perfect.

grid view won't update database (no errors)

I have a page with a details view and a grid view (each with their own data source. I can't figure out why the update says it's successful but don't update the table. the details view works fine.

You should pass the proper parameters to the UpdateParameters section. It looks like you have a copy-paste problem (maybe you copied the section from the InsertParameters section). Your UPDATE statement needs only 3 parameters.

RadGrid(Gridview) Recursive Checkbox in EditItemTemplate Column for Inserts and Updates

I have a RadGrid with a Checkbox inside an EditItemTemplate for an Active or Inactive status.
This checkbox only shows when the item is being updated or added as new. I have a ControlParameter for the checkbox, but since it is recursive with many of these checkboxes in the list, it throws the good old "Could not find control 'cbActive' in ControlParameter" Error.
I dont have any real CS code other than the Radgrid binding on page load.
ASPX Code:
<telerik:RadGrid ID="RadGrid1" runat="server" Skin="Vista" Width="500px"

<UpdateParameters>
<asp:Parameter Name="AccountNumber" Type="String" />
<asp:ControlParameter ControlID="cbActive"

</UpdateParameters>
</asp:SqlDataSource>

You aren't going to be able to set the value through a control parameter; what you can do though, is use an <asp:Parameter> instead, and set the DefaultValue property on the parameter via:
sqlDataSource1.SelectParameters[0].DefaultValue = "X"
Or, with the Grids, I know with the GridView it has a collection of values that it used to perform the update with; you could add an entry representing the checkbox control, which would get pushed into the data source. I know know if the RadGrid has the same option.

So it took a lot of looking around but i couldnt do this without tapping into the commands via the CS. Here is my new Code for it to work:

Casting object to CheckBox in bulk updates

I was following this so far everything is fine with a textbox but when try to modify it to checkbox it gives an error: Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.Web.UI.WebControls.CheckBox'.
Its working when I use TextBox but how can I make all the CheckBox editable in bulk updates?
Here's the sample code behind
private bool tableCopied = false;
private DataTable originalDataTable;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
if (!tableCopied)
{
originalDataTable = ((DataRowView)e.Row.DataItem).Row.Table.Copy();
ViewState["originalValueTable"] = originalDataTable;
tableCopied = true;
}
}
protected void UpdateButton_Click(object sender, EventArgs e)
{
originalDataTable = (DataTable)ViewState["originalValueTable"];
foreach (GridViewRow r in GridView1.Rows)
if (IsRowModified(r))
{
GridView1.UpdateRow(r.RowIndex, false);
}
tableCopied = false;
GridView1.DataBind();
}
protected bool IsRowModified(GridViewRow r)
{
int currentID;
string currentreservedate;
string currentisapproved;
currentID = Convert.ToInt32(GridView1.DataKeys[0].Value);
currentreservedate = ((TextBox)r.FindControl("reservedateTextBox")).Text;
currentisapproved = ((CheckBox)r.FindControl("isapprovedCheckBox")).Text;
DataRow row = originalDataTable.Select(String.Format("reservationid = {0}", currentID))[0];
if (!currentreservedate.Equals(row["reservedate"].ToString()))
if (!currentisapproved.Equals(row["isapproved"].ToString()))
{
return true;
}
return false;
}
}
}

Help would be much appreciated! Thanks in advance!

I think that to answer this question, the contents of the aspx file are required, but I'll try to help. More than likely the element in your form, isapprovedCheckBox, is still set to the the tag asp:Text. As a result the system can't convert the textbox to a checkbox.
Could you include your aspx content as well?

Set current date in formview

I want to put the current date in my formview 'dateadded' but its not showing when I load it in the browser. I'm using code behind but how can I display it with date and time?

You have to use the Databound event for that...
protected void FormView1_DataBound(object sender, EventArgs e)
{
if (FormView1.CurrentMode == FormViewMode.Insert)
{
TextBox dateadded = FormView1.FindControl("dateaddedTextBox") as TextBox;
dateadded.Text = DateTime.Now.ToString("d");
}
}
Edit: You need to pass your Date Column in the inserting method of the DetailsView
protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
e.Values["DateColumnName"] = ((TextBox)DetailsView1.FindControl("dateaddedTextBox")).Text;
}

Instead of doing that in your Page_Load() method, try doing it in the Page_PreRender() method.
