Hi,
Is there any Linq to entities equivalent for DeleteAllOnSubmit??
If not, then is Linq to entities really better than linq to sql? If Yes, then why?
Thanks
|

There is no comparison between the two. Linq to SQL is for, well, SQL. Linq to Entities can be used for a variety of objects. DeleteAllOnSubmit would not make since for this because the entities could be from any type of collection; a list of strings, a list of WMI objects, etc. where delete has no meaning, or a very different one.

seems weird to me but when i try to put a function in a standalone .aspx file i get weird errors
so the file "blah.aspx" starts like:
<%@ Page Language="C#"%>
<%
Response.Write("hellow world");
myFunc();
Response.Write("Bye Bye Cruel World");
bool myFunc()
{
return true;
}
%>
and it won't compile ... says "} expected" and then a bunch of stuff about delegates etc in some randomly named files
anybody got any clue?
thnx

They are allowed, but you have to write your methods within a <script runat="server"> tag:
<script runat="server">
bool myFunc()
{
return true;
}
</script>

as you can see , it is inside the Update Panel , but when i select it flickers. and Below is the code that set the max length of the textboxes
protected void ddlAutoText_SelectedIndexChanged(object sender, EventArgs e)
{
int MaxLength = Convert.ToInt32(ddlAutoText.SelectedValue);
txtUnitLen2.MaxLength = MaxLength;
txtUnitLen3.MaxLength = MaxLength;
txtUnitLen4.MaxLength = MaxLength;
txtUnitLen5.MaxLength = MaxLength;
txtUnitLen6.MaxLength = MaxLength;
txtUnitLen7.MaxLength = MaxLength;
txtUnitLen8.MaxLength = MaxLength;
txtUnitLen9.MaxLength = MaxLength;
txtUnitLen10.MaxLength = MaxLength;
txtUnitLen11.MaxLength = MaxLength;
txtUnitLen12.MaxLength = MaxLength;
txtUnitLen13.MaxLength = MaxLength;
txtUnitLen14.MaxLength = MaxLength;
txtUnitLen15.MaxLength = MaxLength;
txtUnitLen16.MaxLength = MaxLength;
txtUnitLen17.MaxLength = MaxLength;
txtUnitLen18.MaxLength = MaxLength;
txtUnitLen19.MaxLength = MaxLength;
txtUnitLen20.MaxLength = MaxLength;
txtUnitLen1.MaxLength = MaxLength;
}

Is it browser specific or does it happen with all the browsers?

I have seen this behavior but that's IE6 specific.
Let me check if I could replicate it for all browsers. I will get back to you if I find something relevant.

i decided that i should handle the SelectedIndexchange event on the client side. Now its fine it does not Flicker. I even removed the Autopostback and set it to false.
thanks for your time.

I had a similar idea when I saw your code but then I thought that the code you have given may be a part of actual thing that you are implementing. It may require a post-back for server side processing. So I didn't suggest you the JavaScript way of doing this.
Anyways, glad to hear that you finally found a workaround solution.

Hai all,
I want to display confirmation message box in Asp.net code behind (C#).
When I save the record i am doing some validations , in the validation function i need to display confirmation message with "yes"
or "no" , if "yes" the save process should be done and if "no" save process should not be proceed .
I have used Page.ClientScript.RegisterStartupScript() ,but it is not working.
I have also tried btnSave.Attributes.Add("onclick", "return confirm()"); but the confirmation message is opened before save .
I need only at the time of validation .
Please Help me.
Thank u

<asp:Button ID="btnSave" runat="server" Text="Save" OnClick="btnSave_Click" OnClientClick="return confirm('Do you really want to save?');" />
Just use this in your button and I am sure it will work definitely.
|
|
|
|
|
Thanks for the reply
I no need to call the function in onClientClick() , that will work fine .
I need to call the script function only at the server side validation because the confirmation message should work based on the
server side validation.
Thank you
|
|
|
|
|
Can you please show us Page.ClientScript.RegisterStartupScript(), what you've written inside ?
|
|
|
|
|
This is my coding
protected void btnSave_Click(object sender, Infragistics.WebUI.WebDataInput.ButtonEventArgs e)
{
try
{
if (!fnValidate()) return;
else
{
save();
}
}
catch (Exception ex)
{
throw(ex);
}
}
bool fnValidate()
{
Page.ClientScript.RegisterStartupScript(this.GetType(),
"ClientScript", "");
}
Client side function
function confirmUpdate()
{
var agree = vbConfirm(Are you sure do you want to continue ?');
if (agree == true)
{
return true;
}
else
{
return false;
}
}

Hi,
I tried running the following linq to sql query in linq to entity
var req = dbContext.Requisitions.First(r=>r.ID==new Guid(Request["ReqID"]));
I got the following error "Only parameterless constructors and initializers are supported in LINQ to Entities." Any ideas how to go about this?
Thanks

Got a work around, did something like this
Guid ReqID = new Guid(Request["ReqID"]);
var req = dbContext.Requisitions.First(r => r.ID == ReqID);

I need your help guys ...
I have a Listview which contains application names.Multiple items can be selected in it.Now depending on the number of selections made,I have to list all their related testcases in seperate listviews(1 listview for each selection made).
Also the testcases should be come in the listviews in a checkbox format.
So I feel depending on the no. of selections made ,I need to create listviews at runtime(dynamic) and then fill them up with testcases which need to be in a checkbox format.
But I am stuck as to how to create dynamic listview and fill it up.I am not a very experienced coder.
Req doc is like this
· Once the user selects an application a table with all the test cases associated with that application gets displayed.
· If the user checks the check box against the application name then all test cases will get selected.
· Else he can choose specific test cases by checking the check boxes beside the test cases.
My code for 1 listbox selection is as follows and working f9.But this is a satic listview as only one item can be selected.Now the requirement is for multiselect so the situation has changed and I cant use this approach.
Aspx page contains following code:
<asp:Panel runat="server">
<asp:CheckBox runat="server" AutoPostBack="True" Text="Select All" Visible="false"/>
<asp:ListView runat="server" >
<LayoutTemplate>
<table border="1" >
<tr runat="server">
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr id="Tr1" style="font-size: small">
<td>
<asp:CheckBox runat="server" Text='<%# Eval("TestCaseName") %>' Value='<%# Eval("TestCaseID") %>'>
</asp:CheckBox>
</td>
</tr>
</ItemTemplate>
</asp:ListView>
</asp:Panel>
Code Behind is as follows:
protected void lbSelectApplications_SelectedIndexChanged(object sender, EventArgs e)
{
int cobrandId = Convert.ToInt32(ddlSelectCobrand.SelectedValue);
int appid = Convert.ToInt32(lbSelectApplications.SelectedValue);
if (appid != -1 && cobrandId != -1)
{
BusinessLogicLayer.BusinessLogic obj = new BusinessLogicLayer.BusinessLogic();
testcasedataset= obj.GetActiveTestcasesForSpecificCObrandedApplication(appid, cobrandId);
listView2.DataSource = testcasedataset.Tables[0];
listView2.DataBind();
listView2.Visible = true;
chkall.Text = lbSelectApplications.SelectedItem.Text.ToString();
chkall.Visible = true;
for (int i = 0; i < testcases.Tables.Count; i++)
{
ListView lv = new ListView();
//here dynamic creation of listview code should go
}
protected void chkall_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i < listView2.Items.Count; i++)
{
CheckBox chk = (CheckBox)listView2.Items[i].FindControl("chkTest");
if (chkall.Checked == true)
{
chk.Checked = true;
}
else
{
chk.Checked = false;
}
}
}
}
Pls I need ur help.Please advise how to go about itand if you have a better alternative do let me know.
thanks
