Am using a ascx page i want to add a textbox control but its giving me the error like
"
Control 'TopFront1_TextBox1' of type 'TextBox' must be placed inside a form tag with runat=server.
"
I have been trying to achieve the following:
1-Allow the user to change the quantity in a textbox i.e // "txtQuantity"
2-capture the newly entered quantity i.e //int integerNewQuantity= int.Parse(textNewQuantity.Text);
3-update the database using the newly entered quantity i.e. //UpdateItem(data,integerNewQuantity)
Problem:1-I have not been able to capture the text i.e. the newly entered quantity i.e. the value entered in the text box "txtQuantity"
2-Hence the database is updated using the existing value and NOT the new value unless I make a constant assignment as below:
textNewQuantity.Text = "2"; When tested the assignment of any number correctly updates the database. see the c# code:
C# code: Version.1
protected void btnUpdate_Click(object sender, EventArgs e)
{
txtItemDescription.Text = txtItemDescription.Text + "from btnUpdate talking.."; [code]....
I'm trying to use a javascript Date and Time calendar in my Insert and Edit templates in a Detailsview that is bound to SQL Fields. The reason I am trying the javascript date time selector is that I need to have the date and time, the asp.net one is just the date part.
I tried using it with an asp:textbox on just a plain aspx page and it works like a charm, however when I add it to the detailsview i keep on getting the "Error: Object required" am I missing a step here? That and seeing as I'm using a site master page where exactly do I put the:

I am having a gridview with dropdownlist and textbox controls.
I am generating a value in the textbox2 depending on the textbox1 value using the javascript in every row of gridview. In onblur() function of textbox2, I am disabling the textbox2.
Before textboxes, I am having dropdownlist's in every row of gridview. when I disable the textbox2 in the first row and select the value of dropdownlist in the second row, the value of textbox2 in first row is not visible.
I tried by using the viewstate but I am unable to retain the value.

I have a requirement where I have a webpart and two ImageButtons(imgGV, imgLV) and a hidden input textbox('ctl00$MainHeaderContent$txtType') in an aspx page. I need to change templates to this Webpart either to show results in "Grid View" or as "List View" on the click of this ImageButtons. I added code in the page_load of .aspx page as
imgLV.Attributes.Add("onclick", "document.getElementById('ctl00$MainHeaderContent$txtType').value='LV';return true;");
imgGV.Attributes.Add("onclick", "document.getElementById(('ctl00$MainHeaderContent$txtType')).value='GV';return true;");
When I am clicking the specific ImageButton, it has to write into hidden field either "GV" or "LV". In the webpart CreateChildControls I assign templates based on the text in Hidden field either "GV" (Grid Template) else "LV" (List Template). In the CreateChildControls of Webpart for the template change, I am getting the Hidden value as empty. I am using coding as
HtmlInputHidden t = new HtmlInputHidden();
t = (HtmlInputHidden)this.Page.FindControl("ctl00$MainHeaderContent$txtType");
if (t.Value=="GV") {
assign one template}
else { another template}.
I am getting t.Value="". Question is: Is it like if we add some text in a hidden textbox using the Javascript function in an aspx page, the same textbox value in the same aspx page but in the Webpart class in the CreateChildControls method using the code as this(webpart).page.FindControl("Textbox").text is showing empty. So the text added using Javascript into Textbox is it not available in the code behind code using "Text" property of the same Textbox?.

I'm populating my nodes from SQL 2008. My Defauld.aspx is also devided into frames. leftmenu is frame on left. topframe is frame on top and mainframe is frame right center. In my leftmenu frame LeftMenu.aspx display a SQL populated treeview. if I click on the child node it opens Home.aspx in the Main Frame. This is pretty straight forward. My problem is that i can't get the value of that populated node over to a textbox on my Home.aspx page that is displayed in the mainframe on the right. My code is as follows:

Will there any impact master-content page . because script is in content page and html also on same content page.Also let me know you, I am using wizard control where as all these controls are resides on second step of wizard. will that make any impact ?
Edited:
I think wizard control making here matter. As i started my firebug and review the generated html it assign the Id dynamically to those controls which are inside the wizard. thats why javascript unable to find the expected control . eg for txtAmount text box which is inside the wizard control getting name as :
ctl00_ContentPlaceHolder1_Wizard1_txtAmount
but certainly i would not prefer to use this generated Id. So is there any remedy to find control inside the wizard control and get - set values ?

I have a user control the exposes several public properties. I added a reference to the usercontrol to my page and I added an instance of the control:
[Code]....
One of the properties exposed by my control is called "Text". I have used this control in many different projects and I am ordinarily able to do this:
string x = mtPrintPlatform.Text;
However in this project I am unable to use the control as a MetaTextBox...I only see the properties of UserControl, from which MetaTextBox is derived. So my Text property is not accessable.
I am, however, able to cast the control and access the property like this:
string x = ((MetaTextBox)mtPrintPlatform).Text; // this works
This problem occurs with all user controls in my project, I am using just one control as an example.
Im unable to enter apostrophe(') in the textbox as got error message as per below . How to solve this ? Pls help .thanks

how to find Textbox Control inside DetailsView Control Using Javascript, I tried below but gives an error OBject reference not found
document.getElementById('<%=DetailsView1.FindControl("TextBox1").ClientID%>');
I have an implementation of a textbox which inherits from the TextBox control. It currently has some features built in to validate text by some JavaScript that is injected when the control is created. I want to modify this so that the control uses the ASP.NET validation controls (eg. RequiredFieldValidator) instead. Is this possible? Is there a place in the lifecycle of the control where I can programmatically create a BaseValidator control and add it to the form? I want to implement this in my textbox control, rather than each specific page that the textbox is on.

I have 2 - DropdownList controls, which i am filling at severside when page loads. After the user selection in DropdownList1, i am changing the contents in DropdownList2 values. This validation (i.e. changing the contents of Dropdownlist2 values) am doing in Javascript Clientside. But on postback i am not getting the values in DropdownList2. When i say "DropdownList2.Items.Count;" getting "0". I tried to put the contents of DropdownList2 in ViewState on pageload. But i am getting Serialization error at runtime "Viewstate["PersistValues"] = DropdownList2;". I am using html input hidden control to pass the values from server side to clientside for my validation. Now, to meet this requirement i am Binding the DropdownList2 at postback again with first DropdownList1's selected index (This is repeat of logic which i have done in Clientside).
