I assume by "(added) sugar intake from solid foods" you mean something like, "Is higher-than-average sugar consumption from foods (separate from beverages) associated with increased risk of Type II diabetes?" - If that is not correct, please let me know.
Before listing citations to some relevant studies, some brief background information will provide important context for you and others reading this thread.
As you know, the body breaks down carbohydrates (sugars, starches, fiber) into glucose. Consequently, health professionals encourage diabetic patients to not only monitor total carbohydrate intake, but also the types of carbohydrates consumed as well.
One of the most common ways to gauge the impact of a carbohydrate on glucose levels is the glycemic index (GI), and its companion glycemic load (GL).
I mention this fact because while sweet foods, e.g., candy bars, cake, ice cream, etc., tend to have a high glycemic index (GI) and glycemic load (GL), this is not always the case (e.g., watermelon is sweet, but has a low GL), and non-sweet foods high in starch can carry a high glycemic load.

"The Glycemic Index (GI) is a relative ranking of carbohydrate in foods according to how they affect blood glucose levels. Carbohydrates with a low GI value (55 or less) are more slowly digested, absorbed and metabolised and cause a lower and slower rise in blood glucose and, therefore insulin levels."
You can look up many foods' GI and GL on the University of Sydney's glycemic index search engine.

BACKGROUND: Sugar-sweetened beverages are associated with type 2 diabetes. To assess whether this association holds for the fructose-containing sugars they contain, we conducted a systematic review and meta-analysis of prospective cohort studies.
METHODS: We searched MEDLINE, Embase, CINAHL and the Cochrane Library (through June 2016). We included prospective cohort studies that assessed the relation of fructose-containing sugars with incident type 2 diabetes. Two independent reviewers extracted relevant data and assessed risk of bias. We pooled risk ratios (RRs) using random effects meta-analyses. The overall quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.
RESULTS: Fifteen prospective cohort studies (251 261 unique participants, 16 416 cases) met the eligibility criteria, comparing the highest intake (median 137, 35.2 and 78 g/d) with the lowest intake (median 65, 9.7 and 25.8 g/d) of total sugars, fructose and sucrose, respectively. Although there was no association of total sugars (RR 0.91, 95% confidence interval [CI] 0.76-1.09) or fructose (RR 1.04, 95% CI 0.84-1.29) with type 2 diabetes, sucrose was associated with a decreased risk of type 2 diabetes (RR 0.89, 95% CI 0.80-0.98). Our confidence in the estimates was limited by evidence of serious inconsistency between studies for total sugars and fructose, and serious imprecision in the pooled estimates for all 3 sugar categories.
INTERPRETATION: Current evidence does not allow us to conclude that fructose-containing sugars independent of food form are associated with increased risk of type 2 diabetes. Further research is likely to affect our estimates.

QUOTE: "At follow up, 86 participants had developed incident type 2 diabetes. FA [factor analysis] revealed 3 prominent dietary patterns: Balanced Market Foods, Beef and Processed Foods and Traditional Foods. After adjustment for age, sex, waist circumference, interleukin-6 and adiponectin, the Beef and Processed Foods pattern was associated with increased risk for incident type 2 diabetes (OR=1.38; 95% CI 1.02, 1.86). In contrast, the Balanced Market Foods and Traditional Foods Patterns were not significantly associated with type 2 diabetes."

QUOTE: "Substituting 5% of energy intake from vegetable protein for animal protein was associated with a 23% (95% CI: 16, 30) reduced risk of T2D [Type 2 Diabetes]. In conclusion, higher intake of animal protein was associated with an increased risk of T2D, while higher intake of vegetable protein was associated with a modestly reduced risk."
