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 need to bind a List control based on the Gridview Row's datakeyName value while the Gridview control is being loaded into the page. I tried the following but it does not work.The BulletedList control is nested inside a Gridview Control and they both bound to an ObjectDataSource control. In my code, I passed teh UserID into the UserID parameter and call the Select() method but still does not work. Basically, I want to list of a user's hobbies, therefore the hobbies control are driven by the userID. tell me how can I get it to work?
protected void UserGridView_RowDataBound(object sender, GridViewRowEventArgs e) { int UserID;
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.
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.
So I found an example on how to search gridview using filterexpressions on this site (Filter GridView with TextBox using FilterExpression in SqlDataSource in ASP.Net), but now if I try to search with an apostrophe in the textbox, the code fails.
Here's the link to the the article/source - [URL] .....
I have a DetailsViews that I have added a dropdownlist. When I am in the EditBindings area of the EditItemTemplate, click on SelectedValue the "Field Binding" radio button under "Binding for SelectedValue" is grayed out and not available. I have a tutorial that is very clear on how to add a dropdownlist to a GridView or DetailsView and I feel everything is setup correctly. The dropdown box is working with the available choices but is obviously not binding the selected data.
I have a table named RECIPE which is linked to an other table name RECIPE_STATUS
In RECIPE table I have a field named Status_Id which contains the name of the Status which is fetch from the RECIPE_STATUS table based on this ID.
The RECIPE table sample information are as follow :
ID Name Status_Id ==================== 1 Test1 0 2 Test2 1 3 Test3 2
The RECIPE_STATUS entries are as follow:
ID Name ======== 0 Locked 1 Running 2 Free
From an ASP.net page I would like that my user is capable of changing the RECIPE_STATUS from a given recipe. For that I have a DataGrid which is bind to the RECIPE table.
But then what I would like is that the STATUS shown to my user to be the name Locked,Running or free depedning on the Id
How can I bound in my Datagrid the Recipe.Status to be bind to RECIPE_STATUS.Id ?
IN addition to that, If my user change the status for a given recipe, it should be properly save.
I have a hidden value field on a page. On submit I post to a different page. On the page I've posted to I do a Request.Form but I do not get the value just a null value. This is the initial page
The javascript ViewCancellation function is set to a hyperlink in the code behind. The function will have a value like this,<a href="#" onclick=" View Cancellation(54666);return false;">cancel</a>.
I have a DetailsView with some templates. I would like to bind a textbox in one of the templates to a field of a datasource which is not the datesource of the DetailsView. What is the syntax of the Bind() or Eval() code expression to do this, assuming it's possible?
Also where can I find some material on syntax of these "code expressions" and what can be in them?
I realize I'm missing something pretty basic here...
In my XML, it's possible for an apostrophe to appear in a node's value:
[Code]....
If I have controls bound to this XML:
[Code]....
I've noticed that the text is correctly displayed in the asp:TextBox but not in the INPUT element. I'm assuming that it's because server controls correctly escape the apostrophe. To work around this, I tried changing the Description node in the XML to the following:
[Code]....
Again, this displayed correctly in the asp:TextBox, but not in the INPUT element.
My next attempt was to wrap the node's value in a CDATA:
[Code]....
Finally it was displaying correctly in the INPUT element, but now the asp:TextBox displayed the two "& # 3 9 ;". I've even tried "& a p o s ;" but the result is the same.
I have 2 fields in my gridview one called ScriptType the other BagNo, when a user click the edit button, I would like the BagNo filed to be disabled if the ScriptType field is = "TTA" and enabled otherwise. How can I do this?..something along these lines see below..I am using VB..
Need to get access somehow to a by-row value that keeps each row's key. The value can not be displayed as column. The Recovery the value is to be used on a later separate Insert. I need to capture this by-row 'hidden' value on the SelectedIndexChanged event.
how hide this key value so I can recover it on Grid Row Selection?
Gridview have several hidden columns, using DataKeyNames & DataKey to access the information. It works great on the first page, but when select another page and select the row, Get the information from the first page and same row.
I have a grid view, and I add new column as a hyper link field, I want the navigationURL for this field to be Pageexample.aspx?ID=other field value like this
I want to create input inside gridview, the id of the input is set by me. I do want to use HiddenField control because when generating the id of the control, it will set id to gridview_ctrl.....
The input looks like this: <input id="myid01" value="myvalue" type="hidden">. Note that id is generate by me in the code behind.
In ASP.NET WebForms I want to pass arbitrary data from server to client and back again. I am serializing to JSON and have been simply producing JavaScript that creates the object on the client. I have no problem sending data to the server with ajax, but there are situations where I also want to send a Javascript object data back to the server on postbacks. So I guess it needs to be in a hidden field.
1) What is the best way to do this in terms of minimizing complexity and optimizing space and efficiency? In researching this I discovered Protocol Buffers but there does not seem to be a good C# implementation. I did find one, but it was a couple years old and self-described as buggy so that scared me.
2) If I just pass a JSON string, how can I be sure it will be safe to include as the value for a hidden field? Is there any reason I might not want to do this? I could Base64 encode, but it seems like this adds a lot of overhead. What is considered the best or preferred method?
