i am creating a WebCustomControl Following is the code

in RaisePostBackEvent the valu of the textbox is always blank.
I added some textboxes to gridview using following code
<asp:TemplateField HeaderText="STD<br/>ID">
<ItemStyle BackColor="LightBlue" />
<ItemTemplate>
<div style="font-size:xx-small; overflow:hidden;">
<asp:TextBox ID="txtStandard" EnableViewState="true" Height="10" Font-Size="XX-Small" Width="50" Text='<%# bind("STANDARD_ID") %>' runat="server"></asp:TextBox>
<asp:AutoCompleteExtender ID="AutoCompleteExtenderDemo" runat="server"
TargetControlID="txtStandard" ServiceMethod="GetCompletionList"
MinimumPrefixLength="1" CompletionInterval="1000"
EnableCaching="true" CompletionSetCount="20">
</asp:AutoCompleteExtender>
</div>
</ItemTemplate>
</asp:TemplateField>
I want to save updated values to database, But when I try to access values using string strs = ((TextBox)TwoHeadedGridView1.Rows[0].FindControl("txtStandard")).Text;
It always returns me the blank value for all the rows, Same thing happens for dropdown list it returns me originally selected value i.e. value selected at the time of writing dropdown box, there are no duplicate ids present on my asp form , This is my first interaction with customizing gridview, I want to somehow make it run,
I have a simple issue..the user types his/her name in a textbox. Accidentally if a space is entered after a name or before, is it possible for me to trim it while accepting and not raise any error (which actually arises when the textbox is empty)?

View 1 RepliesIn my asp.net+vb web I was using this code to change row colour of gridview
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
If e.Row.DataItem("bloodgp") Is System.DBNull.Value <> True AndAlso e.Row.DataItem("bloodgp") Then
e.Row.BackColor = Drawing.Color.LightGreen
End If
End If
End Sub
Now I want to change the cell backcolour to red for those cells are blank ....
I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.
[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}
So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.
I've noticed that when i populate textboxes from a selected row in a gridview that if the field is blank it displays " " in the textbox.
Here is the solution I came up with. I check each cell before adding it to the textbox.
I get the feeling that I'm either doing something wrong to have this problem in the first place or that there is a better way to handle this.
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
//// Get the currently selected row using the SelectedRow property.
GridViewRow row = GridView1.SelectedRow;
// Load data from selected row into textboxes
if (row.Cells[1].Text.Trim() != " ")
{
txtEditCust_ID.Text = row.Cells[1].Text.Trim();
}
}
I have written a javascript code for handling the password functionality. The scenario is: when user wants to change the old password, he cannot fill the same old password again. I have written the code. But even the simple alert of blank textbox is not working. See the code for reference:
Javascript code:-
<script type="text/javascript">
function ltrim(str) {
var reg
reg = /^s+/g
return str.replace(reg, "")
}
function rtrim(str) {
[Code] .....
aspx code:-
<tr>
<td class="auto-style1">Old Password</td>
<td class="auto-style2">
<asp:TextBox ID="txtOldPassword" runat="server" TextMode="Password" class="txtcareer"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqtxtOldPassword" ControlToValidate="txtOldPassword" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>

Why this is not working...
I am trying to understand the best way of implementing a DropDownList in ASP.NET MVC 2 using the DropDownListFor helper. This is a multi-part question.First, what is the best way to pass the list data to the view?Pass the list in your model with a SelectList property that contains the dataass the list in via ViewDatHow do I get a blank value in the DropDownList? Should I build it into the SelectList when I am creating it or is there some other means to tell the helper to auto create an empty value?

View 2 RepliesI have a project which is developed by using VS 2003 with Framework 1.0.My project works very well while I am testing it on localhost.But 'sometimes' my application will appear blank page after click a save button in the production side(using IE 7).I set 'Try catch' into server codes to detect any error caused after users click save button. And they never see any error description page but 'sometimes' blank page.So I assume my server codes are safe.
View 7 RepliesI would like to create a completely blank aspx page, but I can't figure out how. When I open up Visual Web Developer 2010 Express, and I go to File -> New Web Site, I have a few options. When I choose the ASP.NET Empty Web Site, it does not give me any tools in the Toolbox on the left, so this is no good. But when I choose ASP.NET Web Site, it gives me this template and all of this other stuff. I dont need this 'Welcome to ASP.NET!' template. I'm thinking that I need to choose the Empty Web Site and then Add New Item, but what item? I'm lost!

I am trying to have a listview which will work like a table with paging. My problem is I need to be able to add more than 1 row at a time. ie I want to click "add new row" multiple times on the same page without the page changing and without the rows I'm adding going away.
Basically I need the user to still see the already inserted rows as well as the rows they are planning to insert on the same page. This would mean the page size is temporarily larger than it should be. The new rows would be added to the end of my data source when the user goes to another page or clicks a separate save button.
I've finally figured out an issue I'm have with a zip code field being entered in a text box of a details view in edit mode. I'm trying to understand why i have the issue though. I don't understand why it keeps occurring.his what happens with the zip code field. I've been able to make it reoccur numerous times. If the details view is put in edit mode and the record is updated with the original 5 digit zip code, unaltered in any way, my regular expression validator catches it and doesn't let the update happen. If I change the replace the 5 digit zip code with a new one the update goes through fine. This new value can be a different or the same 5 digits and the update will work. If I don't change the value at all though the update will not go through.
View 8 RepliesI have a method like
public DataRow
GetItem(ENTITY_TYPE
EntityType, long EntityID)
This fetches a row and returns it. Pretty simple.
However I can't test in the method to see if the row was fetched, as the method has to end with:
return ds.Tables[0].Rows[0];
If the row wasn't fetched, this errors as there is no row at position 0.
I can't do this:
DataRow dr;
if (ds.Tables[0].Rows.Count
== 1)
{
dr =
ds.Tables[0].Rows[0];
}
return dr;
.. because then I get an error that I can't return an uninitialised variable (dr).
I can't stipulate what the columns are and return a "blank" DataRow as far as I can see, because it's dynamic so I don't know what the columns will be. There doesn't seem to be a way to instantiate the DataRow return var except by assigning, er, a DataRow. Which I may not have.
I don't really want to switch to using the ItemArray and pass arrays about, I'd rather just pass the DataRow object as this is in a loop which might process a lot of rows.

This is having problems if the phone number is NULL or BLANK. Is there a way to fix it?
