i would like to call the external js file's function onclientclick event, but how can i pass the parameter, which i get from the hidden field value from the same aspx file.
<asp:button id="btn" onclientclick="javascript:test(hidden_field);"/>
I have a user control that i have registered to an aspx page. Now from the aspx page, i am trying to access one of the registered usercontrol's hiddenfield value in my aspx page using javacript using the below code:
tst = document.getElementById('control1$hdnField').value;
I looked into the page's trace, and i could see 'control1$hdnField'. Then why i am not getting its value in my aspx page. I have also confirmed that the hidden field by this name exists in the user control and also has a default value set.
I'm struggling to read an int from the hidden field on aspx page.
<input type = "hidden" id = "myIntegerId" name = "integerId" value= "<%: Model.MyObjectId %>" runat = "server" />
The value is definately on the form, I can see it in the debugger and print it with <%: %>
When I read the form values in the controller, instead of an int I recieve a following string: <%: Model.MyObjectId %>
I have tried casting data in the hidden field to string and calling ToString() method on that field, neither has worked.
The data is submitted using the post event.
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
Is that possible? The reason why am doing this is because I need to parse that variable into a an JQuery function so I wanted JQuery to read that field. Can I Assign that value in base class or I have to do it within default.aspx pageload method?

View 5 RepliesFrom the master page of my ASP.NET site I need to set the value of a hidden field in every get and post request and then subsequently read it in the next request.The problem is that in the post request the code works fine but when the client sends a get request I am unable to read the value of the hidden field from teh Master Page. Is the hidden field the proper approach to this and if so how do I read the value set in the hidden field in the subsequent get request. If the hidden field is not the proper approach for this then what else should I use?

I can't get this to work:
I have a grid view with several TemplateFields. A couple of them are set to Visible=False; each template field has an EditItemTemplate, an ItemTemplate and a FooterTemplate.
[Code]....
While in GridView_RowUpdating event, the value bounded to the EditItemTemplate is properly read
[Code]....
so, debugging ttbImp.Text = "4"; But when trying to get the value bounded to the FooterTemplate, the label contains no values.
[Code]....
so, while debugging, lblImp.Text = "";
why that? I believe it has to do with the hidden visibility of the field, but I can't understand why it reads the value inEditItemTemplate, and it doesn't in FooterTemplate.
I must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change

I've got a gridview with a hidden field, i'm trying to set a value as follows:
value='<%# DataBinder.Eval(Container.DataItem, "Name")%>'
which works in most cases except when the name has an apostrophe like O'Neil. I need to escape the ' if possible.
so i tried: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " /' ")%>' and
value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " //' ")%>'
which doesn't work because of the final apostrophe in the notation i.e. %>' It truncates after the word e.g O'Neil Someone becomes O' which is incorrect.
This works like a charm: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", "'")%>' which isn't good practice as I don't want to hardcode '
I have to pass the value [sysid] for getting the value from another table.

I have a page with several asp labels with no text. I use a click event to add text the fields that have related values from a datareader. In my code I state that if column value of the datareader is null, then make the label visibility false.

I want to integrate paypal inside my shopping cart. For that it requires a html form to be embeded inside .aspx page with the action to paypal and method is post. Inside that form there are some hidden input filed. I want to assign one of those hidden field's value from server side code so i need to access that filed from server side. But how? Here is my form:
<form action="[URL] method="post" id="PaypalForm">
<input type="hidden" name="cmd" value="_cart"/>
<input type="hidden" name="upload" value="1"/>
<input type="hidden" name="business" value="[URL]
<input type="hidden" name="item_name_1" value="Item Name 1" />
<input type="hidden" name="amount_1"/>
<input type="submit" value="PayPal" />
</form>
I want to access amount_1 filed.
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?.
